That tweaker/junkie who steals your bike, breaks into your storage unit, whatever? He's not an organization man. The dude with a standing offer to pay twenty bucks for the bike, or ten if it's shitty? He's with an organization.
What I propose is that we start enforcing the law and treat theft as a crime, not a nuisance or fact of life. Roll up the organizations, toss them in prison, and repeat over and over until the message gets out.
This isn't a problem which can be solved at the tweaker level. What we can do, and simply choose not to, is get every single dude with twenty bucks or a baggie to trade for your bike. All that's lacking is the political will.
