I saw officer smith car jacking across the street from a women's fitness center this morning, noone was injured except his pride.

Actual real news story:

NEWPORT - Sgt. D____ S____, 43, of the Newport Police Department was fired Thursday after he allegedly exposed himself to two women while on duty in his patrol car on Monday.

Smith was allegedly seen masturbating himself while behind the wheel in the police car parked next to a hair salon.

The act of sneakily masturbating onto a car door in such a way that the owner of said car will stick his hand in the mess before realizing it is there when he attempts entry into his vehicle.

The carjacker will typically attempt to do this in a time and place where he can watch the results of his escapades when the owner arrives, without the owner being aware he is being observed.
Hey man, I went out carjacking today and got enough footage to fill my memory stick!
