The "technology" -- as these things are styled -- was introduced, predictably, as a gentle reminder; you're driving faster than whatever the posted limits says you may. Perhaps you weren't paying attention. You are doing 60 in a 55 and so susceptible to being "pulled over" -- that is, forced to stop by the threat of murderous violence if you do not -- and then issued a "ticket," the insipid-sounding euphemism given to the extortion-demand note handed to you by the armed government worker (AGW) who "pulled you over."
Two recent lawsuits challenge the state law that allowed Greenville and Wilmington to set up red-light camera enforcement programs. If successful, the suits would block any N.C. city from operating red-light cameras under that law.
Red-light cameras have once again been declared unconstitutional in North Carolina. No one is surprised because this is the second time RLCs have been declared in violation of state law. Policing for profit, even if it is allegedly designed to benefit the school systems, always has a stench about it.
