We don't use armed police to enforce traffic laws. Police mainly monitor traffic as a revenue device. It's already been proven that monitoring traffic and automating fines in fact promotes reckless driving and causes more accidents than it stops.
In what world? In the US "manual" traffic enforcement is almost exclusively done by armed police and sheriffs. Unarmed civilian traffic enforcement is only done in Berkeley, CA, and a town in Minnesota, afaik.

Do you have a citation for that? There are numerous studies that show significant drops in accident rates in areas with red light cameras. On the order of 10-23%!
