I only mean that all revenues collected from the fines must be distributed to the public at large. They must never be treated as a revenue source for the government.
Sin taxes are meant to reduce bad behavior - or incentivize good behavior. Ideally you'd collect $0 in red-light fines because everyone's following the law. If some politician's budget or private company's revenue stream depends on traffic fines they have adverse incentives. I don't want my city council member voting against traffic safety initiatives because it makes people better drivers and that means less money for some other city program.
Or in the case of a private company contracted to run the cameras, don't give a private company a contract to run the cameras. At least not a contract where they get paid in proportion to the fines collected.
No one should profit off bad behavior. No government program's funding should have to depend on people driving badly.
You're putting those public services and their sources of funding in conflict with each other.
We have this issue with imported deer, that the local hunters will gladly reduce their population, but not to zero. And baits and other methods are prohibited. Deer were likely imported for hunting, and hunters effectively protect the species from eradication by killing off their competition (roos mostly), and permitting them to breed within limits. Not to mention trying to protect them politically.

So yeah, guys walking with rifles in the woods cause deer.
