I actually had the pleasure of writing this one.. as it turns out, I heard it and located the vehicle, a convertable 60's model Chevy, but just as it was parking in the Jack in the Box lot. I went over and looked at it and spoke with the driver brielfy. I warned him it was illegal and he removed it right then and there. Then about a week later (this was the summer of 2005), I heard it again and he also had his stereo blaring (in violation of 27007 CVC). I pulled him over and cited him for 27150.3 (non-correctable as a persistant violation), 27007 and 24004 CVC (a 1 point moving violation).
Then to top things off, he signed his name "Fuck You Pig"
so I amended my citation to add 40504(b) CVC violation (a misdemeanor, for the false signature on the citation) and had the citation charged by the DA in criminal court. Then he shows up and pisses off the judge and gets booked into the jail for contempt of court and had pot in his posession which he brought into the jail at booking.
Needless to say, they threw the book at him. He ended up on 2 years supervised probation after serving 30 days in jail (on a 45 day sentence) and $1200+/- fine, then about 6 months later, he violated probation and went back to jail, there he got into a gang fight (he was a gang-banger after all) that landed him in the Q (San Quentin State Prison), where he sits today.
So, use a whistle tip.. go to State Prison!
