Apparently the guy who shot the suspect wasn't a police officer:

I had no idea they allowed rich civilian donors to play police officers without the regular formal training. It was a disaster waiting to happen, and now it happened.

What I also find strange is that he wasn't able to tell the difference between a gun and a Taser. But I guess that might be down to the fact that he isn't even trained to be a police officer.
