About three years ago, there was an armed robbery in Tom Vogel’s driveway. Three women were walking down one of the quaint, narrow streets in New Orleans’ Lower French Quarter around 1AM when a car crept up and a man jumped out with a gun. The robber grabbed one of the women, ripped off her purse, slipped back into the car, and sped away. Vogel, his wife, and their two dogs noticed nothing. It was the perfect crime.

Except the whole thing was caught on camera.

Soon after the mugging, a detective was in the Vogels’ living room, watching the footage from the Vogels’ four security cameras. The cop recognized the thief’s car and arrested people the next day. “They solved that crime practically overnight,” Vogel says.
