According to the ruling in the case of an innocent homeless man being mauled nearly to death by a K9, police officers who deliberately allow their K9 to maul innocent people will be immune from liability and victims will have zero recourse.
As Slate reports:
The grisly facts of the case are uncontested. One night in 2010, Officer Terence Garrison and his police dog, Bikkel, were tracking a robbery suspect in High Point, North Carolina. Bikkel led Garrison to an abandoned house, then attacked a man crouched behind a bush near the front stoop. Garrison quickly realized that the man did not match the physical description of the suspect. (In fact, he was Christopher Maney, a homeless man accused of no crime.) But Garrison decided that the man might still be dangerous, so he demanded that Maney show his hands before calling off Bikkel. But Maney was using his hands to try to protect himself against the dog and pleaded with Garrison to stop Bikkel's attack, insisting that he had done nothing wrong. After allowing the mauling to continue for 10 seconds, Garrison finally told Bikkel to stop. He then put Maney in handcuffs and called medical support.
