Look, I would rather law enforcement officers be out putting their boot on some rapist's nuts or their elbow into a batter's throat, but they can't do that either. It would hurt the criminals feelings and lower their self esteem.
Sounds like you got busted and still aren't over it. I understand your pain, trust me, but there are very few cases where an officer trumps up a traffic violation just so he/she can write you a $50 ($75, $100, etc.) ticket.
Are there some cities or counties that take traffic enforcement too far? Yes. I live about 15 miles from one called Waldo, Florida. The major revenue generation for the city is traffic violations. But, in large part and across the country, if you got a ticket, you deserved it.
Don't get made at a cop for doing their job. Take your ticket like man, go to traffic school, buy a radar detector (and a scanner?), and go on with your life.
