Yeah, it's simply common sense to show respect to cops, if you don't want them to cause even more trouble for you. However, when cops do stuff like this I not only have no respect for the individuals doing it, but it erodes what respect I have left for the whole profession.
well, DUH! happens to truckers all the time, just like when someone gets pulled over in a car and they are asked for certificate of insurance. The cop has no way to know ahead of time if there is or if there is not one in the car. If not, additional charges.
