It's good they finally, in one city (Montreal has a similar problem), caught a theft ring. But this success just highlights the lack of action against crime that has scaled up to a business. Bicycle theft at scale - easy to find on Craigslist in any college town, corrupt ramp employees at airports steal from checked bags, etc. This stuff is obvious. Yet it goes on and on. Are police resources unbalanced and if a patrol cop can't bluster his way to an arrest it just doesn't happen? Are cops themselves too corrupt and afraid that overtime and detail fraud would start being investigated? What keeps economically significant crime in business?
