I've heard traffic court in America referred to as a "sheep-shearing conveyor belt", and after experiencing it once first-hand believe our bandoleros in blue have found a way.
I called "911" after a burglary years ago and the responding officer was little more than bemused and bored as he filled out a report for the insurance company.
I have beaten 7 out of 10 traffic infraction citations in Georgia to-date. They write tickets like crazy in Atlanta. Sometimes they just pull me over and go fishing.
In three of the tickets, the officer never showed up. Dismissed. In four of the others, I successfully argued before the judge and won.
Never plead Guilty or Nolo Contendre to a traffic ticket. Forcing them to prove their point often yields positive results.
