Well, they don't. The point that I've tried to make--and I speak for my jurisdiction--is that we conduct checks on CPIC and on the individual just in running the plate. That may not be the individual in the vehicle; that's just to whom it is registered. Those queries come back, and from there on, if an officer feels the need, he can delve deeper into the individual he's dealing with.
