The police chiefs in Missouri's two largest cities are asking the state Supreme Court for guidance on red-light camera ordinances, which are increasingly being called into question.
St. Louis chief Sam Dotson and Kansas City chief Darryl Forte wrote in an open letter on Thursday that inconsistent rulings from lower courts have led to confusion for police and municipalities that operate red-light cameras.
It wasn't clear if or when the Supreme Court would take up the issue. A message left with a court spokeswoman on Friday was not returned.
Dozens of Missouri communities use the cameras. Police say they can save lives at dangerous intersections. Opponents question their constitutionality and contend the cameras are aimed at generating revenue, not public safety.
