Why wait for an autopsy? Blame TAZER! Hang the cop.
Maybe dude was a Dopehead? Some people do crazy $hit.
Three members of my family are cops and all had to go through a Tazer hit, while in training.
Addendum: My recommendation on this particular incident would have bee a 12 gauge load of #7 shot at his legs!
That’s what I use on Looney birds.
