If you were making a stop of a suspected armed robber, would you let him reach for the glove box?
Around 25 years ago I was the target of a felony stop. It was past mind eight and I was alone on the road. All of a sudden I was surrounded by six cops with their guns drawn on me and I was ordered out of my car. They wanted me to open my trunk. I knew I had a cooler full of beer in my trunk. I am asking about the Constitutionality of the search. I was told to not be stupid and open the trunk. In the blink of an eye they were all gone, except for one cop, who then told me my car matched the description of someone who just robbed a party store. He then said “isn't it good to know we are doing our job?” and then raced off.
Surely you must agree that if the officer asks him to produce documentation, and he moves to produce that documentation, he shouldn’t be shot up for obeying the command.
If there was any reason to believe he may have been extremely dangerous, then it makes sense to get backup, and to order him to exit the vehicle with his hands up.
