Oh C'mon--It's not everyday a cop gets called to yank a half dressed female out of a car she refuses to budge from. If the cop didn't ask questions of the woman driving an out of state car how this bimbo ended up in a stupor in her car, he wasn't doing his job. "I found her on the side of the road" at 1 AM sure wouldn't cut it with me. At a minimum the officer should have peeked in the windows of the car and called in the license plate.
The point is, it wasn't a serious matter, even if it was strange because of the way Crystal was dressed. It was nothing more than a public intoxication incident at 1 am. Shelton probably figured she was just another drunken hooker down on her luck who drank too much and got put out of a car by some john. It happens all the time. The point is, it wasn't a serious matter at the time that required an investigation so there was no reason to hassle Kim - just a public intoxication incident.
Cops get calls all the time to deal with drunks - all day long - starting in the morning and escalating at night.
