I don't understand this system: Are you giving them a break or what? I took the above photo in one of the main parking lots in Calgary and that's warn the thieves of the possibility of being caught while doing their usual business.
Nevertheless I don't think these guys who are actually professionals would ever be distracted or misled by these bites. Yes may be in the beginning but not now.
