Since this thread is from 2005 and a lot has changed nowadays i think we should have a sticky with the most latest "police powers" somewhere for each state. Maily to do with when police pull you over. If you are doing something illegal and get caught thats your own problem, but if you are doing nothing wrong and are targetted due to the vehicle you drive, you should know all your rights.
There is a lot of information that most of us don't know and police know that we don't know this information and therefore bend the rules a lot.
I for one don't know most of the rights police have when they pull you over and usually just do exactly what the polics officer asks, even letting them search my vehicle. I'm sure if we knew a lot more to it, it would make future situations easier.
Just a thought.
