Oof, what a callous asshole. That ladies comments about that guy of "We don't need you" is spot on. Someone with such casual treatment to an innocent death has no business being any where near a position of authority.
I've been reading about this story but this is the first time watching the footage. Wow, that is a lot worse than I imagined. I was thinking maybe the officer just made a bad joke to help ease what just happened but this guy seems to be genuinely having a great day at work.
