BRASHER, Circuit Judge: 
      This appeal is about a traffic stop for an  unusual temporary tag that ended in a fatality. Troy Robinson, a passenger in  the stopped vehicle, inexplicably fled the scene on foot. He ran across a busy  road and through a dollar-store parking lot before attempting to scale an  eight-foot wall and escape into a nearby apartment complex. What happened next  is hotly disputed. But a reasonable jury could find that the pursuing officer,  Casey Benton, fired his taser at Robinson while he was on top of the wall and that  the shock from the taser incapacitated Robinson, causing him to fall, break his  neck, and die. Robinson's family sued, Officer Benton asserted the defense of  qualified immunity, the district court rejected that defense, and Officer  Benton appealed. After a thorough review and with the benefit of oral argument,  we affirm in part and reverse in part. We conclude that Officer Benton cannot  be held liable for conducting the traffic stop or pursuing Robinson when he  fled. On these two issues, we reverse the district court. But we hold that  Officer Benton's decision to tase Robinson at an elevated height violated  Robinson's clearly established right to be free from excessive force. On that  issue, we affirm.  
I. BACKGROUND
On the day of Robinson's death, Officer Casey Benton of the DeKalb County Police Department was patrolling near The Highlands of East Atlanta apartment complex in Atlanta, Georgia. That area had recently experienced a rise in gang related and violent crime.
      Around 7:00 p.m., Officer Benton observed a  white SUV with a temporary license plate leaving the apartment complex shortly  after it had entered. He decided 
      to follow. The SUV was driven by  Wilford Sims and its lone passenger was Troy Robinson. Sims had bought it a few  days earlier. Officer Benton later testified that he decided to follow the car  because he could not see an expiration date on the temporary tag. While Officer  Benton was following Sims's car, he looked at the temporary tag and ran the tag  number in the police department's computer system. He does not recall the  information that was returned by the computer system about the tag, nor did he  check the system to see whether the tag was expired. Sims was not suspected of  committing any other traffic violations. After about two minutes, Officer  Benton stopped the SUV.  
      Officer Benton asked for Sims's driver's license, and Sims  provided it. Officer 
    Benton then asked whether there  were any weapons in the car. Sims advised Officer Benton that he was carrying a  handgun. Officer Benton asked Sims to step out of the vehicle, and Sims  complied. Officer Benton then retrieved a loaded handgun from the center  console. Officer Benton told Sims that he could reenter the car, which he did.  Officer Benton then asked Robinson if he had any identification. Robinson  replied that he did not. 
There were two other officers on the scene: Officer C.M. Franklin and Officer L.O. Niemann. When Officer Benton asked one of them to run Robinson's name in the police department's system, Robinson abruptly exited the vehicle and fled on foot. Robinson ran across a road and through the parking lot of a Family Dollar store that abutted the apartment complex. Officer Benton pursued him on foot while Officer Niemann attempted to follow in his patrol car. Officer Franklin remained with Sims.
    At some point  after Robinson reached the area behind the Family Dollar, Officer Benton fired  a single shot from his taser without warning, striking Robinson. The ground  behind the store slopes down toward a chain-link fence that, on the day of the  chase, was surrounded by thick undergrowth. The fence stands several feet from  an eight-foot-high concrete wall that lines the back of the Highlands apartment  complex. By the time Robinson reached the chain-link fence, Officer Benton was  still ten to fifteen feet behind him. Robinson  went over the fence and tried to climb the concrete wall, fell off the wall,  and suffered blunt force trauma to his head and neck that caused his death. 
    Officer Benton  testified that he fired his taser without warning while Robinson was still on  the ground. As Officer Benton tells it, the taser did not affect Robinson  because only one of the two taser probes pierced Robinson's skin, with the  other getting stuck in Robinson's clothing. Consequently, Officer Benton  stopped his taser short of a full five-second cycle. Robinson proceeded to  climb up the fence, then onto the wall, where he lost his balance, fell, and  died. 
      Robinson's family tells a different story. In their version  of events, Officer 
      Benton fired his taser upward at Robinson  while he was on top of the wall. The taser 
    probes contacted Robinson with  full effect, causing him to become temporarily incapacitated, fall, break his  neck, and die. The plaintiffs point to substantial evidence that contradicts  Officer Benton's account. First, several days after the incident, another  officer investigating the shooting found a green blast door from a taser  cartridge inside the complex, on the opposite side of the wall from where  Officer Benton was standing when he fired his taser, suggesting that the taser  had been fired upwards and over the wall. Second, several eyewitnesses from the nearby apartment complex testified  that they saw Robinson fall. One witness testified that she heard a "pop" while  Robinson was still visible on top of the wall. Another witness testified that he heard Robinson "yell 'help'  three or four times" while on top of the wall. That witness testified that she  saw Robinson sitting on the wall until "something occurred" and "[h]is right  arm went in the air" before he fell. A third witness said that he also heard  Robinson call for help while sitting on the wall. He then saw Robinson "stiffen  up" like "he went into shock" before falling over the wall into the apartment  complex. 
      Officer Benton testified that he was aware  of and understood police department policy that a taser "will cause most  everyone to fall and therefore should not be used when the risk of falling  would likely result in death[.]" He also agreed that under that policy it was  "not appropriate" to use a taser "if someone is at an elevated height[.]" Tracy  Rucker, the master instructor on taser use for DeKalb County, testified that a person  who is tased will experience "neuromuscular incapacitation" and will be  paralyzed from pain for around five seconds. He also testified that he  instructed DeKalb County officers that tasers could be deadly when the target  is in a dangerous position such as an elevated height. And he affirmed that  even a fall "from a level that's not that high" can cause serious injury when  the victim has been incapacitated by a taser.  
      Officer Benton  never issued a ticket to Sims for a traffic violation. The temporary tag on  Sims's vehicle did have an expiration date and was valid. Officer Benton later  testified that he never felt like Robinson posed an immediate threat to him or  any of the other officers. The officers found no weapons on Robinson's body,  and there is no other evidence he had a weapon. A posthumous toxicology report  revealed traces of marijuana in Robinson's system. The record does not explain  why Robinson ran away from the traffic stop. 
      Robinson's mother  and his nine surviving children sued under federal and state law. Their  complaint included the following claims: (1) a 42 U.S.C. § 1983 claim against  Officers Benton, Franklin, and Niemann for seizing Robinson; (2) a 
      Section 1983 claim against Officer Benton for pursuing and  tasing Robinson; (3) a Section 1983 municipal liability claim against DeKalb  County; and (4) state law claims against Officer Benton for pain and suffering  and wrongful death.  
      Officer Benton  moved for summary judgment. He argued that the plaintiffs' federal and state  law claims against him were barred by qualified immunity and official immunity,  respectively. Regarding the Section 1983 claims, he argued that he was entitled  to qualified immunity for the traffic stop, the pursuit of Robinson, and the  tasing of Robinson. Specifically, he argued that (1) he had reasonable  suspicion to conduct the initial stop; (2) he had reasonable suspicion to  pursue and seize Robinson after he fled; (3) his use of force against Robinson  was not excessive; and (4) even if his conduct was arguably illegal, he did not  violate law that was clearly established.  
      The district  court granted the motion in part and denied it in part. The district court  concluded that official immunity shielded Officer Benton from the plaintiffs'  state law claims against him. But it also concluded that he was not entitled to  qualified immunity from the Section 1983 claim. Officer Benton appealed.  Because the district court's denial of qualified immunity is an immediately  appealable collateral order, we have appellate jurisdiction. See Hall v. Flournoy, 975 F.3d 1269, 
      1276 (11th Cir. 2020) ("[W]hen legal  questions of qualified immunity are raised . . 
      . interlocutory appellate jurisdiction  exists."). 
II. STANDARD OF REVIEW
We review an order denying summary judgment based on qualified immunity de novo. See Helm v. Rainbow City, Ala., 989 F.3d 1265, 1271 (11th Cir. 2021). On a motion for summary judgment based on qualified immunity, courts "must construe the facts and draw all inferences in the light most favorable to the nonmoving party and when conflicts arise between the facts evidenced by the parties, [they must] credit the nonmoving party's version." Id. (quoting Feliciano v. City of Miami Beach, Fla., 707 F.3d 1244, 1252 (11th Cir. 2013)). "Summary judgment is appropriate if 'the evidence before the court shows that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.'" McCullough v. Antolini, 559 F.3d 1201, 1204–05 (11th Cir. 2009) (quoting Haves v. City of Miami, Fla., 52 F.3d 918, 921 (11th Cir. 1995)).
      "Qualified immunity shields public  officials from liability for civil damages when their conduct does not violate  a constitutional right that was clearly established at the time of the  challenged action." Bailey v. Wheeler,  843 F.3d 473, 480 (11th Cir. 2016)). In other words, an officer is entitled to  qualified immunity unless he (1) violated a constitutional right, and (2) that  constitutional right was clearly established at the time. See Helm, 989 F.3d at 1272. These two elements may be analyzed in  any order. See Pearson v. Callahan,  555 U.S. 223, 236 (2009). If the evidence at the summary judgment stage,  construed in the light most favorable to the non-movant, contains "facts  inconsistent with granting qualified immunity, then the case and the qualified  immunity defense proceed to trial." Stryker  v. City of Homewood, 978 F.3d 769, 773 (11th Cir. 2020). 
III. DISCUSSION
This appeal is about Officer Benton's qualified immunity defense as to three separate actions: the initial traffic stop, the pursuit of Robinson, and the tasing. We address each in turn.
A. The Initial Traffic Stop
The district court denied Officer Benton's motion for summary judgment as it pertained to the initial traffic stop, concluding that a jury could find that Benton lacked reasonable suspicion. On appeal, Officer Benton argues that the district court erred because he had a particularized and objective basis for conducting the stop. We agree.
    Under the Fourth  Amendment an officer may "conduct a brief, investigatory stop when the officer  has a reasonable, articulable suspicion that criminal activity is afoot." Illinois v. Wardlow, 528 U.S. 119, 123  (2000) (citing Terry v. Ohio, 392  U.S. 1, 30 (1968)). Reasonable suspicion "is a less demanding standard than  probable cause and requires a showing considerably less than preponderance of  the evidence[.]" Id. at 123–24  (citing United States v. Sokolow, 490  U.S. 1, 7 (1989)). Still, it requires "a minimal level of objective  justification for making the stop." Id. 
      We consider whether a "particularized and  objective basis" for the stop existed in 
    light of the totality of the  circumstances. Brent v. Ashley, 247  F.3d 1294, 1300 (11th Cir. 2001). 
    Here, Officer  Benton had a particularized and objective basis for the stop. He testified that  when he first observed Sims's vehicle, he could not see the expiration date on  the tag. And he testified that he  stopped Sims because the temporary tag on Sims's vehicle appeared to be in  violation of state law requiring an expiration date to be displayed. O.C.G.A. §  40-2-8(b)(2). Driving with an  improper tag is a misdemeanor. Id. Further, the other police officers who were questioned about the temporary tag  on Sims's vehicle all believed that it looked unusual enough to warrant suspicion.  These officers specifically pointed to the placement of the expiration date as  justification for their belief. Officers Franklin and Niemann said that the  look of the tag would have caused them to stop the car. We have examined  photographs of the tag in the record and concur that the date's location on the  tag could lead a reasonable officer to believe that the tag was improper.  Accordingly, we have little difficulty in concluding that Officer Benton had  reasonable suspicion to make the stop. 
    The plaintiffs contend that the record  contains evidence that could lead a jury to conclude that Officer Benton merely  used the tag violation as a pretext for an otherwise unlawful stop. But Officer  Benton's subjective purpose for conducting the traffic stop is immaterial. See Whren v. United States, 517 U.S.  806, 813 (1996); see also United States v.  Holloman, 113 F.3d 192, 195–96 (11th Cir. 1997) (traffic stop of a vehicle  whose tag light was out did not violate the Fourth Amendment, even though the  search was conducted as part of a wider anti-narcotic operation). Under the  reasonable suspicion standard, we need not guess at Officer Benton's motivation  for initiating the stop. We need only consider whether, given the totality of  the circumstances, an objective and particularized basis for the stop existed. Brent, 247 F.3d at 1300. Here, one did. 
B. Officer Benton's Pursuit of Robinson
    The district  court also held that because Officer Benton failed to establish that the  initial stop was lawful, he necessarily failed to establish that his pursuit of  Robinson was lawful. On appeal, Officer Benton argues that Robinson's headlong  flight from the traffic stop justified pursuing him. Again, we agree with  Officer Benton. 
      Whether Officer Benton had reasonable  suspicion to pursue Robinson turns on the totality of the circumstances. See United States v. Gordon, 231 F.3d  750, 757 (11th Cir. 2000) ("[W]hether reasonable suspicion exists must be  determined on a case-by-case basis in view of the totality of the  circumstances."). Even though Robinson was merely a passenger in a vehicle that  Officer Benton stopped on suspicion of driving with an invalid tag, his behavior  was suspicious enough to warrant pursuit. When Officer Benton asked another  officer to run Robinson's name 
    through the computer system,  Robinson fled the traffic stop by sprinting across a busy road toward the  apartment complex. The Supreme Court has held that "[h]eadlong flight—wherever  it occurs—is the consummate act of evasion," and though "[i]t is not  necessarily indicative of wrongdoing, . . . it is certainly suggestive of  such." Wardlow, 528 U.S. at 124. See also United States v. Franklin, 323 F.3d 1298, 1301 (11th Cir.  2003) (reasonable for officers to pursue someone who ran away); Gordon, 231 F.3d at 755 (same). Under  these circumstances, Officer Benton did not violate the Constitution by  pursuing Robinson on foot.
C. Officer Benton's Tasing of Robinson
 
    The district court denied Officer Benton  qualified immunity for killing Robinson, concluding that a jury could find  Benton's use of force was excessive. On appeal, Officer Benton argues that his  use of force against Robinson was objectively reasonable and not excessive.  Alternatively, he argues that the unlawfulness of his use of force was not  clearly established at the time of the incident. We disagree. 
      1.            Officer Benton Violated  Robinson's Constitutional Right to be Free from 
      Deadly Force 
      Officer Benton  maintains that he fired his taser while Robinson was still on the ground. But  the plaintiffs point to evidence in the record—eyewitness testimony  contradicting Officer Benton and a taser cartridge's blast door on the far-side  of the wall from where Officer Benton was standing—suggesting that Officer  Benton fired his taser while Robinson was in a precarious position atop the  eight-foot wall. On a 
    motion for summary judgment, we  resolve doubts about the record in favor of the non-moving party. See Stryker, 978 F.3d at 773. So, for  the purposes of our analysis, we assume that Officer Benton fired his taser  while Robinson was atop the wall, temporarily paralyzing him and causing him to  fall, break his neck, and die. We are tasked with deciding whether Officer  Benton's use of force in this context—shooting a taser aimed at a person on top  of an eight-foot wall who was unarmed and not suspected of committing any  particular crime—was excessive. 
      We have little  trouble in concluding that this use of force was excessive. The amount of force  used by an officer "must be reasonably proportionate to the need for that  force." Lee v. Ferraro, 284 F.3d  1188, 1198 (11th Cir. 2002). "'The "reasonableness" of a particular use of  force must be judged from the perspective of a reasonable officer on the  scene,' and the inquiry 'is an objective one.'" Smith v. LePage, 834 F.3d 1285, 1294 (11th Cir. 2016) (quoting Graham v. Connor, 490 U.S. 
    386, 396–97 (1989)). A court  cannot apply this standard mechanically. Kingsley  v. Hendrickson, 576 U.S. 389, 397 (2015). Instead, the inquiry "requires  careful attention to the facts and circumstances of each particular case." Graham, 490 U.S. at 396.  
    We therefore consider "the relationship  between the need for the use of force and the amount of force used; the extent  of the plaintiff's injury; any effort made by the officer to temper or to limit  the amount of force; the severity of the security problem at issue; the threat  reasonably perceived by the officer; and whether the plaintiff was actively  resisting." Kingsley, 576 U.S. at  397. When an officer uses deadly force, we must also consider whether the  officer (1) "'has probable cause to believe that the suspect poses a threat of  serious physical harm, either to the officer or to others' or 'that he has  committed a crime involving the infliction or threatened infliction of serious  physical harm'"; (2) "reasonably believes that the use of deadly force was  necessary to prevent escape"; and (3) "has given some warning about the  possible use of deadly force, if feasible." McCullough,  559 F.3d at 1206 (quoting      Vaughan v. Cox, 343 F.3d 1323, 1329–30 (2003)); see also Cantu v. City of Dothan, Alabama, 974 F.3d 1217, 1229 (11th Cir.  2020). 
      Here, a  reasonable jury could find that Officer Benton applied deadly force, that is,  force that an officer "knows to create a substantial risk of causing death or  serious bodily harm." Pruitt v. City of  Montgomery, Ala., 771 F.2d 1475, 1479 n.10 
      (11th Cir. 1985). We have recognized that a taser is  generally not a deadly weapon. Fils v.  City of Aventura, 647 F.3d 1272, 1276 n.2 (11th Cir. 2011). But like many  other weapons, a foot, or a fist, a taser may be used to apply deadly force. See United States v. Guilbert, 692 F.2d  1340, 1343 (11th Cir. 1982) ("[W]hether an object constitutes a 'dangerous  weapon' turns not on the object's latent capability alone, but also on the  manner in which the object was used," especially "when used in a manner likely  to endanger life or inflict great bodily harm."). As relevant here, we 
    join many other courts that have  recognized that tasing a person who is at an elevated height may come with a  substantial risk of serious bodily harm or death. See PerozaBenitez v. Smith, 994 F.3d 157, 168 (3d Cir. 2021) (collecting  cases); Baker v. Union Twp., 587 F.  App'x 229, 234 (6th Cir. 2014) ("It is widely known among law enforcement . . .  that tasers should not be employed against suspects on elevated surfaces  because of the risk of serious injury from a resulting fall.").  
    Moreover, again taking the facts in the  light most favorable to the plaintiffs, Officer Benton knew that he was using  deadly force when he tased Robinson on top of the wall. He had been trained  that a person who is tased will experience "neuromuscular incapacitation" and  will be paralyzed from pain for around five seconds; more than enough time for  Robinson to lose his balance and fall from atop the wall. In his deposition,  Officer Benton was asked if he understood department policy that a taser "should  not be used when the risk of falling would likely result in death, for example,  on a roof or next to a swimming pool." He replied that he did. He was then  asked if he agreed that it was "not appropriate" to use a taser "if someone is  at an elevated height[.]" He replied, "I agree." Cf. Lombardo v. City of St. Louis, Missouri, 141 S. Ct. 2239, 2241  (2021) (when deciding whether to grant summary judgment on an excessive force  claim, relevant facts include departmental instructions and other well-known police  guidance). Accordingly, considering the facts in the light most favorable  to the plaintiffs, Officer Benton applied force that he knew created a  substantial risk of serious bodily harm or death. 
    We also conclude  that Officer Benton's decision to use this level of force was not reasonable  under these circumstances. This is so for three reasons. 
      First, Officer  Benton lacked "probable cause to believe that [Robinson] posed a threat of  'serious physical harm'" to anyone. Cantu,  974 F.3d at 1229 (quoting McCullough,  559 F.3d at 1206). Robinson was unarmed and never made any move indicating that  he was about to draw a weapon. The gun in the center console of the car  belonged to Sims and had already been retrieved by Officer Benton, eliminating  the possibility that Robinson had taken the gun. Robinson made no threatening  gestures of any kind. There is no evidence that he posed a threat to anyone in  the apartment complex, which he had just left. There is no objective evidence  in the record suggesting that Robinson was dangerous at all. This lack of  evidence accords with Officer Benton's subjective impression of the situation;  he testified that he never felt like Robinson posed an immediate threat to him  or any of the other 
    officers. 
      Second, Officer Benton did not have  probable cause to believe Robinson had committed a crime "involving the  infliction or threatened infliction of serious physical harm." McCullough, 559 F.3d at 1206. In fact,  Officer Benton lacked probable cause to believe that Robinson had committed any  crime. See Cantu, 974 
    F.3d at 1229; Graham, 490 U.S. at 396. Robinson was  not the driver of the vehicle that Officer Benton stopped for a suspected tag  violation. The vehicle was driven by and belonged to Sims; Robinson was merely  a passenger. And although Robinson's flight from the traffic stop was  suspicious, that act alone would not give a reasonable officer probable cause  to believe that Robinson had committed crimes involving the infliction of  serious physical harm. 
      Third, Officer  Benton fired his taser at Robinson without warning. "When considering whether  it was feasible for a police officer to warn a suspect that []he plans to use  deadly force, we consider both time and opportunity." Cantu, 974 F.3d at 1231. Officer Benton had both. He was never more  than a few seconds behind 
    Robinson and had eyes on him  throughout the entire chase. He could have ordered Robinson to stop or warned  him that he intended to fire his taser if Robinson failed to comply. Instead,  he waited until Robinson was on top of the wall before firing his taser at him  without warning, causing him to fall to his death.  
      Accepting the plaintiffs' version of the  facts as true, Robinson posed no threat of serious physical harm to anyone. Nor  was he suspected of committing a crime involving the infliction or threatened  infliction of serious physical harm. He was not even the suspect of the traffic  stop; the vehicle was owned and driven by Sims. Nevertheless, Officer Benton  applied deadly force without warning to prevent Robinson's escape on foot. Under  these circumstances, Officer Benton's use of deadly force was objectively  unreasonable. 
      
    2. The Tasing Violated Clearly Established Law 
    To prevail, it is not enough for the  plaintiffs to show that Officer Benton violated Robinson's Fourth Amendment  right to be free from deadly force. They must also show that the right in  question was clearly established at the time of the incident. The ordinary way  of showing that a right is clearly established is by showing that "a materially  similar case has already been decided." Mercado  v. City of Orlando, 407 F.3d 1152, 1159 (11th Cir. 2005) (citing Harlow v. Fitzgerald, 457 U.S. 800, 818  (1982)). "We do not require a case directly on point, but existing precedent must  have placed the statutory or constitutional question beyond debate." Ashcroft v. al–Kidd, 563 U.S. 731, 741  (2011). A plaintiff may also show that a "broader, clearly established  principle should control the novel facts [of the] situation." Mercado, 407 F.3d at 1159 (citing Hope v. Pelzer, 536 U.S. 730, 741  (2002)). To control a novel factual situation, a broad principle "must be  established with obvious clarity by the case law so that every objectively  reasonable government official facing the circumstances would know that the  official's conduct did violate federal law when the official acted." Waldron v. Spicher, 954 F.3d 1297, 1305  (11th Cir. 2020) (quoting Loftus v.  Clark-Moore, 690 F.3d 1200, 1205 (11th Cir. 2012)). 
    In either case, only prior decisions  from the United States Supreme Court, this Court, or the relevant state supreme  court can put officers on notice regarding the constitutionality of their  actions. See Crocker v. Beatty, 995  F.3d 1232, 1240 (11th Cir. 2021).
      The Supreme Court  has held that the existence of materially similar caselaw is "especially  important in the Fourth Amendment context." Mullenix  v. Luna, 577 U.S. 7, 12 (2015) (quotation marks omitted). To defeat a  qualified immunity defense without a materially similar precedent on point, a  Fourth Amendment plaintiff must show that an officer's "conduct lies so  obviously at the very core of what the Fourth Amendment prohibits that the  unlawfulness of the conduct was readily apparent to the official." Cantu, 974 F.3d at 1232 (quoting Smith v. Mattox, 127 F.3d 1416, 1419  (11th Cir. 1997)). She "must show that the official's conduct 'was so far  beyond the hazy border between excessive and acceptable force that [the  official] had to know he was violating the Constitution even without caselaw on  point.'" Id. at 1232–33 
    (quoting Priester v. City of Riviera Beach, Fla., 208 F.3d 919, 926 (11th  Cir. 2000)).  
    This case passes  both tests: the right in question was clearly established by a materially  similar precedent and was obviously clear in any event. 
    First, there is a materially similar  precedent: Tennessee v. Garner, 471  U.S. 1 (1985). There, the Supreme Court held that a police officer used  excessive force when he shot an unarmed burglary suspect to stop him from  fleeing on foot. See Garner, 471 U.S. at 21. The Supreme Court has cautioned us against  relying on the holding of Garner to  the extent that holding is "cast at a high level of generality." Brosseau v. Haugen, 543 U.S. 194, 199  (2004). But we are concerned with Garner's  analogous facts, not Garner's  high-level holding. Garner clearly  established that an officer cannot use deadly force to stop an unarmed man who  is not suspected of committing a violent crime from fleeing on foot. That is  precisely what happened in Garner and  that is precisely what happened in this case. Accordingly, Garner put Officer Benton on notice that he could not use deadly force  to stop Robinson from running away on foot. 
    To be sure,  there is one factual distinction between this case and Garner. In Garner, the  officer shot the suspect with a gun. Here, Officer Benton shot Robinson with a  taser. But that is a distinction without a difference. As explained above,  taking the facts in the light most favorable to Robinson, Benton used deadly  force when he shot Robinson off the eight-foot wall with a taser. That is, he  used force that he knew would "create a substantial risk of causing death or  serious bodily harm." Pruitt, 771  F.2d at 1479 n.10. He used this level of force to stop an unarmed man who was  not suspected of committing a violent crime from fleeing on foot. Garner establishes that this level of  force is excessive in that circumstance.  
    Officer Benton argues that the law was not  clearly established on this point because of our unpublished, nonprecedential  opinion in Harper v. Davis, 571 F. App'x 906 (11th Cir. 2014). We  disagree. In Harper, police officers  responded to an emergency call about an armed man who "had been drinking all  day and taken methadone" and who was "pointin' guns at everybody" and "beatin'  on his wife." Id. at 908–09. Around 10:30  p.m., the officers donned bullet proof vests and tracked the suspect into the  woods. When they found the suspect hiding in a tree with a gun, they shot him  with a taser, causing him to fall and suffer serious injuries. Id. at 910. We recognized that the  officers had used "significant force" that "border[ed] on deadly force" when  they shot the suspect with a taser while he was in the tree. Id. at 912. But we reasoned that the  officers had qualified immunity because of the seriousness of the suspect's crimes  and the threat that the armed and violent suspect posed to the safety of the  officers and to others. Id. at  913–14. Unlike the suspect in      Harper, Robinson was neither armed nor suspected of committing a  violent crime. But, despite lacking these justifications, Officer Benton used  the same significant degree of force against Robinson that the officers used in Harper. Accordingly, our nonbinding  opinion in Harper does not support  Officer Benton's position. 
      Second, we would conclude that the use of  force here was obviously unconstitutional even absent a case directly on point.  Robinson posed no immediate threat to Officer Benton. He never tried to harm  any of the officers, nor did he make any threatening movements or gestures. The  officers also had no reason to think he posed a threat to anyone in the  apartment complex, which he had just left. He was not suspected of committing a  crime involving the infliction of serious physical harm. He was not even the  suspect of the traffic stop, which was conducted on the suspicion that Sims was  driving with an illegal tag. Yet, without any warning, Officer Benton applied  deadly force to prevent Robinson's escape from the traffic stop on foot. We  conclude that no reasonable officer could have believed that the application of  deadly force was warranted under these circumstances. See Cantu, 974 F.3d at 1235 (an officer violated the Fourth  Amendment with obvious clarity by, without warning, shooting a non-violent  suspect who had tried but failed to grab the officer's taser); Mercado, 407 F.3d at 1159 (an officer  violated the Fourth Amendment with obvious clarity by, without warning, firing  a high velocity projectile at a suspect who, though he had a knife and was  threatening suicide, was non-threatening toward the officers).  
IV. CONCLUSION
We see no constitutional infirmity in  either Officer Benton's decision to conduct the initial traffic stop or to  pursue Robinson on foot, and we reverse the district court's ruling as to those  two issues. Regarding the main issue in this case— Officer Benton allegedly  tasing Robinson on top of the wall, causing him to fall, break his neck, and  die—we affirm the district court's denial of Officer Benton's motion for  summary judgment on qualified immunity grounds, and remand so that the plaintiffs' claims against Officer  Benton relating to the tasing may proceed to 
      trial.
