Least competent criminals

Jazmine Roberts, 19, was apprehended by a Neiman Marcus security guard in White Plains, N.Y., in August and held for police after she allegedly walked out of the store with a $250 pair of jeans and raged against the guard. According to a police report, Roberts was under the impression that once she walked out the door, she was immune from arrest, telling the guard, "It's too late. I already left the store." ¦
