Hard to second guess. A taser might have worked, but this guy obviously had heart problems. Would it have been any better if a taser would have ignited a heart attack?
Probably not. This was just one of those things that happened.
It all could have been avoided had this guy just surrendered to his arrest and then called an attorney.
I do doubt this cop wanted this guy to die.
He was just standing there talking to the officer in front of him when he was tackled. The tackle came out of nowhere. That wasn't DUE PROCESS. It was judge and jury once again were the bad cops. There are good cops too.
