Something else to keep in mind is that a paladin may not necessarily care. He may not trust you, and will be watching you a little closer, but if you're not doing something both evil and opposed to his goals (a paladin of Set, for example, would probably not be too concerned with a petty drug dealer), he's probably not going to concern himself with you.
Or he might even see you as a necessary evil. Think of Star Trek: Deep Space 9. Quark was a known criminal and troublemaker, and the station's captain confronted him on the first episode, saying he was turning a blind eye to some of the more ... questionable activities, as long as the egregious ones were curtailed.
