Wasting police resources

US police grapple with rise of 'swatting' pranks

When Florida police got a call from a man who said he shot four people at rapper Lil Wayne's house this month, they responded as they are trained to.

Heavily armed, flanked in body armor and accompanied by sniffer dogs, officers surrounded the Miami mansion after the alleged shooter told the 911 dispatch: "I'm killing whoever else I see..."

But police found no shooter at the house, and no victims. Lil Wayne was not there either.
