Local jurisdictions are heavily incentivized to hand out infractions of any kind -- deserved or not. Why? Because they keep the money.
What do they spend the money on? Things like public employees and their benefits, including pensions. It's clearly a perverse incentive.

I've always thought that government shouldn't benefit from fines or seized property. I'm not sure what a good solution is. Perhaps they should take the money from fines and just light it on fire.
There shouldn't be a financial incentive for governments to hand out tickets and fines and seize property - the democratic incentive should be enough.
