Anarcho-tyranny. It's not so much to catch the career criminals as it is to make sure that no political organizing can happen on any scale major enough to disrupt the machine. The criminals are encouraged in order to terrorize the public so that they beg for bigger government, higher taxes, and more centralized control structures. The elite running the show don't actually care about "little people." Any care that actually takes place is incidental, more up to the local constabulary or local officials who aren't completely on board with the bigger picture.
