If I was a cop, I'd ticket everyone I ever saw do this. The world isn't your damn ashtray; throwing butts out your window is disgusting, trashy behavior. So I think a ticket is well warranted. Sexual assault is a different matter though. Now excuse me, I have to make a ffone call.
Unless the patrolman is side by side with the motorist, or tailgating them, there is no way in the world you can see someone throw a cigarette butt out the window. To me it’s just a convenient excuse to pull someone over, about like seeing them with no seat-belt on and pulling them over, which is just another reason for stopping someone, then acting like they are a mass murderer on the loose.
