There's no disincentive.
You have to look at the different levels of criminality. Of course, there are smaller operations that are doing it because other people are doing it and it's accepted. If they get a knock on the door from the police, they're going to give it up. But the ones we have the biggest problem with are the hard-core criminals, where time and time again you go after the same people, take them back to the same court system, and they just get an increase in fine.
