After a week had gone by, I was talking with my neighbor and told him about it and he said that he had a motion-sensor video camera that was directed at his front yard (driveway). He checked it out and this is the crime in progress. This is footage from his house (we share a mailbox, so it kind of picks up what's going on in part of my front yard).
This is the first video that show the kids rolling up on their bikes and scoping the place out. They notice my open garage and go in for the kill. Once they're all out of screen the video stops.
The motion-sensor camera picks up the perpetrator on his way out.
We showed this to the police, but of course they have better things to do than worry about a stolen bike.
