When did police stop trying to catch robbers? It's usually just a few serial robbers terrorizing a neighborhood. The few times they catch someone they stop like 50% of the crime in the area. I remember one time they did a bait bike program and rounded up a ring that was stealing hundreds of bikes. But they see one little robbery and go meh!
