As everyone should.
Everything he did put people at risk that day -- even his partner and the public.
He started firing while the car was still in motion and before his partner could prepare himself and take cover. I'm sure his partner with 11 years experience in LE was shocked by this.
Was he trying to show off his shooting skills to the new guy that he could hit a stationary target from a moving car??
And some of his rounds were recovered from within neighboring houses meaning that people in those houses were in the line of fire.
And regarding the gun pointing at him, all anyone needs to do to see which direction the rifle was pointing is take a stick or broom handle, put it in your left hand and then turn sideways to the right -- what's in your hand is the last thing to turn.
What was in Andy Lopez's hand was the last thing to turn as well and it was in no way threatening to the deputy.
I didn't know that, but I trust that you have been following this. I haven't kept up with subsequent articles, except one that said that the whole incident may have happened in less than 10 seconds including the 8 shots fired by the officer.
