Missouri cities planning to install red light cameras after the Missouri legislature rejected their use would have no legal sanction according to Jay Nixon, the state's Attorney General.

"I think it's pretty clear these pictures can't be the sole or only evidence to cite drivers for violating state traffic laws," Nixon told the St. Louis Post-Dispatch. "I have deep concern whether taking someone's picture rolling through a stop light is adequate evidence in and of itself to uphold a state traffic law. A picture may be worth a thousand words, but a picture in and of itself is not a conviction."

Arnold, Missouri has enacted a local ordinance and is ready to install red light cameras, but it is unclear how the city will proceed following the attorney general's comments questioning the legal validity of the tickets they produce. Creve Coeur is also actively considering ticket cameras, but the city council has not voted to approve them. Around the country, several states have found that the devices led to an increase in overall accidents.
