Sorry, but I have some sympathy for the judge's position. Being able to leave a bike around on the streets might be a nice thing to be able to do but I don't think anyone here would think it a practical thing to do these days. The police doing it will just tempt opportunists into taking it rather than what we are really after which is the people who will go after a locked bike. In this case they caught someone with an obvious record but that was more by luck than anything. Focus on trapping the people that go after our locked up bikes not just some opportunist who sees an opportunity in an unlocked bike.
