Talk about bad luck, a man in San Francisco recently snatched an iPhone from a lady, only to find himself arrested less than 15 minutes later. He was arrested so quickly because the woman was actually part of a real-time GPS demonstration.
SFGate - Problem was, the woman was carrying the phone as part of a company's demonstration of a real-time GPS tracking program. If the bandit would have taken a peek at the screen, he would have seen himself traveling across a map of San Francisco.
Toure was captured a half-mile away about 10 minutes later, at 4:01 p.m., said police Sgt. Troy Dangerfield. He was booked into jail on suspicion of grand theft and possession of stolen property.
As far as positive demonstrations go, it can't get any better than this. To find out more about this slightly hilarious situation, cick here.
