I've heard tales of cell towers having more or less automatic interference detection and the owners have a big incentive to let the FCC know. For other things, it's so rarely enforced or "self-policed" (like ham bands) that it's super rare for people to get busted, even with triangulization being what it is. Some kid here in NYC was trolling on the NYPD frequencies (analog FM still) and it took quite a while to track him down.

There are so many cops going around with stingrays I sort of doubt that the FCC can be too aggressive about this stuff. I'd guess that the interference would have to be relatively major for them to show up very fast.
