there are times when the police probably go too far, too fast. there are most likely times that they reach for a gun before the need to, or react overwhelmingly forcibly.
this isn't one of those times. there was no way, especially once all the evidence was collected, including gunpowder on the 'victim' which indicates extreme close range when shot, that this cop was ever going to be charged with anything.
there was a struggle for the gun, which put the cop in fear of his life.
