I found some news articles that seem to back up this stat. It wasn't all attributable to the cameras though. It also included targeted enforcement strategy with bait cars and what not.

Source please. This does not sound credible. How does scanning license plates stop people from breaking into parked cars?

I haven't validated your statistic (and it's unclear what "in the long run means" since this is a point-in-time thing), but assuming it's true, how do you determine it is causation and not correlation?
