He was on fentanyl. Fentanyl can be fatal. He was complaining that he couldn’t breath before the officer put his knee on his neck. There’s no reason why being on his neck would have killed him.
Bottom line: there are no evidentiary grounds for charging the police officer with murder.
It was all politics from the getgo. The police walked into a trap.It had been planned and set well in advance. The Police walked squarely into a trap.
