would be to make a mandatory minimum yellow light time of 4-5 seconds. That would kill almost all ticket cameras revenue, do more to improve safety, and save lives and property damage. If someone's running a light after 5 seconds of a yellow on most roads, there's little room for argument they need a ticket. I suspect however once the revenue drops, the cameras will be pulled, which will be proof enough it was always about the money instead of the safety.
It's similar to what I've said about other legal matters. If suddenly everyone obeyed the laws there would be few to no police, courts, prisons, bail bonds, criminal lawyers, probation officers, etc. The reduction of such is something each bureaucracy does not want to see happen. To avoid it they then must "manage crime" not try to eliminate it. Another move is to increase the number of laws, define more infractions. Our entire legal system is effectively in cahoots with the criminals to keep crime at a certain level that will justify the same. It's always about the money. When levels of crime drop, more criminals find probation and parole, because the system then needs them back out there to justify their existence and to lessen the chance of cutbacks of their power structures, their particular bureaucracy. Crime does pay. It pays the judge, the lawyers, the prison personnel, bail bondsmen, and a whole host of related jobs.
None of these above are interested in a crime free society, even if such could exist.
