I live in the vicinity of these stolen bikes. My concerns are, was it the type of lock? The way the bike was locked (not locking the frame, just the tire, etc.)? Where the bike was locked, ie a fence because there was no bike rack? Gotta make sure we're protecting ourselves as much as possible.
I'm not sure which kind of locks these folks are using. I have heard from a 2 victims that they had cheap cable locks. In almost all these cases the lock and bike was gone.
