This drives me NUTS! If a police officer pulls you over for anything and asks for anything within his rights for the stop, you do that action. Period. If you run its because you did something wrong either just now or previously and don't want to talk to the cops.
The cops don't know why you're running. Does he just not want to talk? Is he creating distance so he can bring out a firearm without obstruction? Is the suspect creating a distraction so a second party can do them harm?

If you run from the police you deserve what you get.

There are cases where the cops are totally and completely in the wrong. However, more often than not, when you have a split second decision to make your reaction is going to be self preservation in whatever form makes sense in that nanosecond.
