Finding this activity is as easy as falling off a log. If you want to try this for yourself, you are literally minutes away from meeting a bike thief. He'll have 10-20 bikes on the cheapest locks on a campus bike rack, especially this time of year, or he'll set up a sketchy meeting as in this story.
WTF are cops doing if they are not busting patently obvious theft rings? Making this kind of bust should be utterly basic police work. It should be what the new guy does on his first day. Oh, right, they are raising revenue and fighting the long ago lost Drug War or looking for non-existent "terrorists." This is why policing has utterly disconnected from quality of life and middle class concerns.
