This is very simple, a man died in custody how did he die and who if anybody was responsible.
Yes, but also - why was he in custody if he broke no law?
The cops are being charged with illegal arrest of the man. They chased him without probable cause, and they arrested him even though his knife was legal.
Cops should be punished if they just pick up random people off the street, who have committed no crime in the first place.
IMO, there are a few sections here. 1) why was he thrown in van despite no crime, 2) what/whose actions fucked him up, and 3) which cops, if any, were aware of his messed up medical situation and didn't alert EMS as he begged for it.
It's easy for some getbiggers (not you, others) to just claim he was a punk, he deserved it. But if they put themselves in the same position - handcuffed, locked up, hurt somehow and begging for medical care, then dying alone on floor of police van... that's a horrible fate for anyone to endure, much less someone who broke no law.
