> In fact, these consequences would be more severe for public servants like cops.

I absolutely agree with this. Police officers need to uphold a higher standard.

> If the cop wants to lie to get a conviction, they should be able to do it BUT also pay for their lie.

The problem is that while an individual police officer might be not very willing to do things like write false and questionable tickets, police administrators and local government people would love that extra income without having to raise taxes (or do other things that invite scrutiny or would make them look bad). I bet if things like these were admissible, there would be pressure to go get them and fabricate the backstory on how the evidence/information was obtained. Granted things like this already happen but I am afraid this might even make the blue code of silence stronger.

Individual police officers are people and have ethics and morals. However, they are subject to bribery, coercion, and promise of a reward for conforming like anyone else. I'm afraid the risks of allowing fruits of poisonous trees would outweigh the benefits.

Step 0 of fairness. Separate the incentive from the enforcement. Fines shouldn't benefit to the same entity who pays the police.
