Exactly. See Chicago's photo red light debacle. And that's a case where otherwise I'd support the idea because running red lights kills and maims people with a much higher incidence than say speeding on the highway.

The two speeding tickets I've gotten: one was deserved, but I still fought it for a minimal (standard) plea bargain reduction. The other, the cop flat out lied twice. He said he used pace method, yet was never going the speed I was (he came upon me like a bullet and I wasn't speeding); but then the ticket had the radar box checked, and I said I wouldn't sign it until he corrected it. He said he wasn't going to change the ticket and if I didn't sign it he'd take me to jail. Small podunk town in Kansas just randomly pulling people over to make money. Modern day highwayman.

Both you and the OP are being pretty black and white about this. Paying for speeding tickets you deserve because you were speeding is hardly "loving cops so much".

My comments parent did say fighting "without a lawful defense." I'm pretty sure that fighting an invalid ticket is a lawful defense.
