The big objection to traffic cameras is that their real purpose is to raise money for local government. If that is so, what we should do next is obvious.
Right. Install a lot more of them. It is a brilliant idea, and the whiners are all wet. Instead of forcing our proverbially hard-working citizens to pay taxes, put the burden on the scofflaws who endanger lives on the streets.
Since traffic fines can be avoided through the simple expedient of obeying the law, public services will thus be funded with voluntary dollars. You can’t refuse to pay taxes, but whether or not you risk incurring a fine is entirely your choice. Taxes, moreover, hit the poor disproportionately, whereas they can easily go through life without paying a penny in traffic fines.
