If you flag the dozen or so people that come in to your business once a week to steal, you don't have to have as much surveillance in the store otherwise. Just check them out when they enter, very simple. For instance, Costco has a much lower theft rate (0.11–0.2% of sales) compared to other supermarkets (1-4%) simply because they manage to keep criminal out through membership fees. Control the entrance, target the known criminals and we can go back to a high trust society.
