Now this one is rough. While clearly the victim here would not have died had he been healthy it does not excuse the actions and escalations of the police. They immediately resort to physical take down methods the moment the man shows signs of not understanding them.
They then proceed to pin this man and ignore his cries as he dies. While a healthy male would have survived this encounter this was not the case here. The man was disabled and obese and that is why his heart gave out, but it never should have come to that. There was no reason to start violently grappling with him in the first place, he was not being threatening just drunk and confused.
Another example of how sub human cops can be.
