The Christchurch New Zealand mass shooting (where Brenton Tarrant GoPro recorded himself shooting a bunch of Muslims) also had hinky shit happen in the video. The ejected bullet casings were literally disappearing in mid air. I think he also shot out of his front windshield when he got back in his car, and later footage showed no damage to the windshield. If I remember correctly, there was also no blood seen in that video either.
