3%? That seems fine, lock your bike to a light post and keep it overnight, I estimate the likelihood it's going to be stolen at 100%.
Of course, with both cars and bikes, police have much more important to do. That's the invariant: whatever the crime, there is surely something more worthy of their attention out there, so nothing is ever done.
Don't think parent is making an argument, just an observation. From personal experience where I live, most people wouldn't bother to even report a stolen bicycle or broken car window because there's so much more serious crime (gang violence etc) that police will inevitably treat your "petty" case as less important. It's terrible, but it's just the way of things in some places.
Want to solve more car break-in and bike theft cases? Authorize the police to roll the helicopters and armored personnel carriers to catch suspects. We've bought police all these toys and their not going to want to work a case unless they get to use them.
