CHICAGO - Leaving your boyfriend is one thing. Leaving him when you're the getaway driver ... well, that's how he ends up a Dumbass of the Day.
Chicago police say Kameron Alston mugged a man -- less than two blocks from mayor Rahm Emanuel's house. Alston's girlfriend was allegedly waiting for him to wrap up ... when neighbors realized what was going on and called 9-1-1.
Once she spotted the officers, she took off. Wwith no ride, Alston tried to outrun the police. His eventual arrest secured his spot as our Dumbass of the Day.
