I'd like to know what policies shops have in regards to bicycles of suspicious origin (possibly stolen).

Here at the bike dump we have a strict policy to not trade or buy bikes.  But, we also don't ask or check about nice bikes found in alleys, garbage, donated, or pulled out of the river.  We don't usually say anything when someone comes in with a nice bike to fix missing the back wheel and seatpost, or tries to sell a Trek 8000 for $20.

I know there are lots of stolen bike registries out there, but do any of the co-ops take the time to check?  What do you say when someone brings a bike to fix that was likely stolen at some point?  Do you ask for or record serial numbers? 

Obviously, asking where they got the bike from based on profile alone is a really shitty thing to do.  Stopping scruffy looking native guys for questioning because they are riding a nice bike is the sort of thing the asshole cops do.
