Unless this kid was 7' 2" at that weight, he had poor eating habits, probable high blood pressure and hypertension.
Based on what you are saying, their wasn't a lot else the police could do and this was a reasonable use of force in this situation.
Are the police to allow this giant kid to kill someone else first?
If this kid was breaking windows out in a Home, that flying glass could have killed other kids.
Also, lots of over violence he was displaying could have killed others.
Despite the age, if this kid was being really dangerous to others, it is best he died first before others.
He could have always cooperated and avoided the whole thing.
I see no reason to sue or go after the police for anything here.
Maybe they do want to change procedures and put nets in the cars to throw over some of these people.
I know the issue with a net is you can't search the person well and that is also a danger to the police.
Everything is too complicated these days.
He sounds like one of those that usually having a mental disease or behavior problem that often leads to being easily angered with high levels of rage. Usually a take down and a few hours in a secluded room with an IM will temporarily take care of the problem. These patients typically have NO impulse control. Just the type the mental hospitals were originally designed to treat or house. I can't believe he wasn't on some type of legal medication.
The medical induced 3 day coma tells me he was probably on a respirator for three days after the event.
