It was 1 bullet passing thru 2 people. Killing the first person in line. Even if a cartridge had a bullet in it, why did he point it at his cinematographer? Should have been a stunt person, a rustler, a water bucket, or a robber. Only other feeling I have is that someone placed a live round into a 'safe' cylinder deliberately because of all the other problems and disgruntled workers on the set. He want's to call it a 'tragic accident'. It was no 'accident' IMHO. Just like police don't call car wrecks an 'accident'. It's a crash.
