HOUSTON - A 911 operator is accused of hanging up on people calling for help. Investigators say that Crenshanda Williams had thousands of "short calls", lasting less than 20 seconds. In one call, a security guard reported drivers drag racing. Moments later, investigators say that Williams hung up. The recording captures her saying "aint' nobody got time for this. For real." Williams reportedly told investigators she often hangs up on callers because she didn't feel like talking with anyone at the time.
