I think he is playing the intent angle and implying that the dead cinematographer was collateral and not the intended target. Killing a few people makes an assassination look less like an assassination. Personally I think negligence will probably be the better explanation, libshit cali cucks don't have any firearm discipline. Diversity hire firearms guy left a live round in the chamber or something. I'm having trouble buying the 'debris' theory, I can't see a fatality from a pebble unless it was point blank.
