"The man was under control and no longer fighting", said David A. Harris, a University of Pittsburgh law professor who specializes in police conduct.
Andrew Scott, a former Boca Raton, Florida, police chief who now testifies as an expert witness in use-of-force cases, agreed, saying the officers should have at least rolled him on his side so he could breathe.
The death was “a combination of not being trained properly or disregarding their training,” Scott said. “He couldn’t move. He was telling them he couldn’t breathe, and they ignored him. I can’t even describe it. It was difficult to watch.”
The New York City officer in the Garner case said he was using a legal maneuver called
“the seatbelt” to bring down Garner, whom police said had been resisting arrest.
But the medical examiner referred to it as a chokehold in the autopsy report and said it contributed to his death.
In Minneapolis, kneeling on a suspect’s neck is allowed under the department’s use-of-force policy for officers who have received training in how to compress a neck without applying direct pressure to the airway. It is considered a “non-deadly force option,” according to the department’s policy handbook.
A chokehold is considered a deadly force option and involves someone obstructing the airway. According to the department’s use-of-force policy, officers are to use only an amount of force necessary that would be objectively reasonable. Chokehold maneuvers are banned under New York police policy.
