Couple motion sensors inside that trigger some really bright lights, then a video camera complete with overly bright "on" light....Keeps the honest people honest, anyway.... Oh yeah, good friends with the Chief of Police....the cop shop is down the alley south two blocks, next door to the North of me is a Convenience store..... At least a half dozen times a day theres a squad car cruizin' down the alley from the cop shop to the C-Store....maybe the 1st three rules of real estate helps, too....Location, location, location!!!!!!
