Read the article. Interesting that the DA himself went public to discuss the shooting. Why? Was there some sort of outcry that I didn't hear about? Or was it because BJ Baldwin is a public figure and his father is connected to the "gaming" industry?
Wolfson might be from the old school of cops and prosecutors that aren't all that comfortable with citizens defending themselves, but at least he calls it right when he sees it. I'd rather have that guy as DA and hate his stance on gun control than have a San Francisco style DA who lets criminals go free and prosecutes cops.
Also, bad things happen fast. Dead criminal was pissed off he couldn't buy a gun and was wandering around in a bad mood. For whatever reason, Baldwin became the target. Notice that he took cover and returned accurate fire, killing the aggressor.
