This a surveillance video taken in New Orleans this past Saturday morning where you'll see a man run up to a guy walking down the street and point a shotgun at his face. Only, it doesn't quite turn out the way the thief expected.

From the NOPD Youtube page :

On Saturday, 4/27/13 at or about 5:05AM, the victim was walking in the 1900 block of Burgundy when he was approached by an unknown black male. The subject pointed a shotgun at the victim's face and stated give me your money. The victim disarmed the gunman and then chased him. Moments later the victim was approached by two black males in a black four door sedan (possibly a Honda Accord). The driver of the vehicle said to the victim "give me my gun back and I'll give you your phone that you dropped". The victim then used the shotgun to strike the rear windshield of the vehicle causing it to break.
