Background - On May 20, 2012 Trooper Thomas Black encountered Hansen’s unleashed German Shepherd (Conan) running in the southbound lanes of I-29 near St. Joseph, Missouri, causing vehicles to swerve and a ~1/4-mile traffic backup. - Black attempted multiple non-lethal means to remove or scare the dog off the roadway (calling, running, sirens, shouting); the dog repeatedly evaded capture. - Black fired one shot from ~50–70 feet, wounding the dog; the dog continued moving in the lanes on its front paws. - Black fired a second shot; the dog reached the median and Black fired two additional shots to kill the dog. - Hansen sued under 42 U.S.C. § 1983 claiming an unreasonable seizure (Fourth Amendment). The district court denied Black’s qualified-immunity summary-judgment motion; Black appealed. - The Eighth Circuit reviewed de novo, framed the claim as an excessive-force (degree of force in seizing property) issue, and reversed the district court, granting qualified immunity. ### Issues | Issue | Hansen’s Argument | Black’s Argument | Held | |---|---:|---:|:---| | Whether shooting and killing the dog was an unreasonable seizure under the Fourth Amendment | Shooting was excessive because after the first shot the dog was disabled and could have been removed without further force | Use of force was reasonable to clear a continuing, serious public-safety hazard on a busy interstate when non-force attempts failed and no other tools were available | Court: First shot reasonable; subsequent shots also reasonable given continued obstruction and safety risk — no Fourth Amendment violation for which qualified immunity is unavailable | | Whether Black is entitled to qualified immunity | The law clearly established that officers may not shoot pets that do not pose imminent danger (district court relied on Andrews) | Precedent did not place this conduct “beyond debate”; no controlling case holding it unconstitutional to shoot an unrestrained dog creating serious highway danger | Court: Existing precedent did not clearly establish that shooting an unrestrained, dangerous highway dog violated the Fourth Amendment; qualified immunity applies | | Proper legal standard for force claims involving property (dog) | N/A (focus on whether force was reasonable once dog was disabled) | Force must be judged from perspective of a reasonable officer on the scene, not with hindsight | Court: Apply objective-reasonableness test from Graham/Kingsley; district court erred by relying on calm-after-the-fact judgements | | Whether owner’s possessory interest precludes killing an escaped dog | Hansen: retains sufficient property interest that shooting was unreasonable once dog was disabled | Black: owner’s possessory interest diminishes when dog runs at large and becomes a public nuisance; officer may use force to abate public-safety risk | Court: Owner’s interest wanes when pet runs at large; officer’s seizure (including deadly force) can be reasonable when public-safety risk persists | ### Key Cases Cited De La Rosa v.
