Trigger happiness? I just watched a Chris Rock video again about how not to get your but kicked by the police. One of them was not to run. Running in a vehicle toward the police and potentially over the police would induce the bringing force to the situation.
When a police officer brings a gun to bear on a person and they continue to flee they should be shot as far as I am concerned. If they are willing to risk the use of deadly force against them they must need it.
