Just a thought for the Metro Nashville Police

Obviously, I'm not a cop, so I could be talking out of my you-know-what on this. But since the West End Attacker seems to be doing the same thing time after time (looking for homes where purses are in plain view through a window, breaking in a window or door, snatching the purse and fleeing) why don't the police set up a sting operation? Find some concerned homeowner in one of the targeted areas who's willing to cooperate, set up a purse in a conspicuous place, and have some cops hide in a closet or outbuilding in wait for him to strike? It might take awhile (or it might take more than one house) but he'd probably eventually take the bait. Sure, it might not work, but so far the "let's wait in the neighborhood with the police 'copter and squad cars at the ready" hasn't done the trick, has it?
