Not certain whether he died from their actions or an unrelated health condition?
Answer me this, I jump on a guy for refusing to talk to me. I then hold him down and he dies while I'm on top of him. What will happen to me when the police arrive?
A. Nothing
B. I'll be arrested for murder
Further, will the DA care whether cause of death was asphyxiation, a ruptured aorta, a heart attack, or an aneurysm ? I don't think so, as my action was what led to it.
