....”The dude died from his own weight”....
Even if so...the guy kept telling them he couldn’t breath many times over....so the Grand Jury had to have something we are not privy to.
I can see that he could be killed by his on weight pressing on his chest.
But he is the one who caused that situation by resisting arrest.
I do not see why the officer should be charged with trying to effect an arrest that resulted in an accidental death.
I see no malice here.
I don’t think anyone was out to kill that guy.
