The actions by the police jurisdiction 40-20 is talking about are known in police circles as 'attitude pinches'.  If you have a big mouth, you can get quite a few of those in a very short time.  It's also referred to as 'selective law enforcement'; the police 'select' an individual or group and enforce the law against them.  That's the basis for 'profiling'.  The equipment tickets are always easy, especially for a teenager  in the '60's who is trying to have his car as 'cool' as everyone else's.   

My son had a unique car as a teenager.  He kept getting pulled over because the police wanted to look at it.  He didn't have a big mouth so he never got any tickets, even though I would bet an equipment violation was on that beast somewhere. They just said "Nice car, kid.  Good luck finishing it up."
