are we free to murder anybody who you consider being ripe for disposal? who is the arbiter that decides which individuals are or aren't ripe for disposal
at the time he was on the ground with 3 officers pinning him down, he was not a threat to the officers or anybody. no justification for the use of deadly force from that point forward. he was was previously resisting arrest and so violent and destructive that lethal force was somehow needed to protect people, then THAT was the time to use force, not once he's on the ground and restrained.
