Of course not. But when you direct someone to get their ID there is a reasonable chance that it could be in the vehicle. Thus reaching into the vehicle should not have been unexpected.
The officers first mistake was not asking the driver if he had his ID on him. When he replied "No" then the officer should have had him stand in front of the vehicle while the officer recovered the ID.
At the point that the driver reached inside the vehicle (due to the officers poor handling of the situation up to that point) the officer was justified in pulling his weapon and taking cover, however he was not justified in using deadly force against someone holding a wallet that the officer requested he get.
This hot-rod was way to fast on the trigger and failed to properly identify the threat.
I totally agree with you. Lots of bad choices all piled up at the same time and the situation went to $h!t real quick.
Ummm... No. That would be an unreasonable search. The man was stopped for a seat belt violation. If he asks about the ID, the man would say "It's in my wallet, in the car." At that point the man - NOT the officer - is allowed to retrieve his ID.
