"In enforcement, you always have to have both a focus on the really worst actors - you know, gang bangers, in this case, drug dealers, that sort of thing - but also routine enforcement because think about, for instance, the IRS. They don't say, OK, well, if you're not a money launderer, it doesn't matter whether you fill your tax return out right or not. They have both. They go after the really bad actors and they have a kind of general, routine enforcement."
