This is terrible. Sounds to me like the victim was following the law. Upon being stopped he followed concealed carry law which is to announce your concealed carry permit and to tell the officer he had a gun. People normally carry the prof of insurance and registration in their glove compartments. I believe the girlfriend said that was what he was reaching for. Listen to the officer, he sounds out of control. I think he very much over reacted in this case. Having said that I think it's a shame that the cops have so unjustly been vilified. I think it is now going to be necessary that all cops work in pairs.
from what i have been reading
the cop also said for him to stop reaching
and the guy failed to do so
in the video the cops says
" i told him to stop reaching ..."
that is when the girlfriend corrects him
"you told him to get his id his drivers license"
So the victim was doing as told (get his license) and the cop, thinking he was reaching for a gun, but not seeing one, shot him four times.
I'm guessing that cop will be looking for a less stressful, slower paced job requiring less decision-making. A donut factory line worker seems appropriate.
