What the hell? I got into my car today and I noticed that the door was unlocked. I thought well I must have forgotten or something.

Then later on I noticed that there is a cigarette butt on the driver side, and I don't smoke.

It's very odd, maybe someone broke in, but it's not to steal anything. I have nothing of value in the car. I don't notice any CD's or even the loose change missing.

I also noticed a cop car patrolling in my neighborhood, leaving right as I was parking my car into my spot.

Now ... I'm a paranoid person to begin with but I start thinking:

-> A smoker broke into my car at night, drove my car to do some criminal activity. The cops got my license plate from some witnesses and is patrolling the neighborhood looking for it.
