He was armed... with a 2 ton weapon. If, as they say in the news reports, the guy tried to run over a couple cops, they may very well have been justified in using deadly force. I imagine video of those incidents probably exists (from some of the other squad cars) but we didn't get to see those.
According to what I read, that's why the first officer shot at the car about half way through the video. We couldn't see what was going on over where the offenders car was.
I've watched and rewatched the end of the video and can't tell but the officer that was on the hood claims he was hit by the car, throwing him onto the hood. If that turns out to be true, it'll likely be ruled a good shoot. He was on the car, the car was moving and he was at risk of incurring great bodily harm or death.
The officers involved are on paid administrative leave, which is pretty standard after a shooting, until the investigation is completed.
Could it have been handled differently, with a different outcome? Of course. There are almost always several options. But, we're playing armchair quarterback here. We're looking at a very tiny slice of the evidence and making judgements.
If the officer on the hood actually was hit and thrown onto the hood, I'll be obligated to retract my earlier statement about days off. I made that statement without doing anything other than watching the video. I know better and have since collected a little more information. My bad.
The fact is, none of us have all the information that is available to the investigators who will make a final determination in the case.
I don't like it much when edited or partial videos like this are released. They frequently show a biased view of the actual events, causing people to react, sometimes negatively.
