Many of the cameras were yanked because of illegal practices. Here's on instance in a city in TN:

The city of Chattanooga, Tennessee will refund $8800 in red light cameras tickets issued to motorists trapped by an illegally short yellow time. Municipal Court Judge Russell Bean on Monday dismissed charges against 176 vehicle owners cited by an automated ticketing machine located at Martin Luther King Boulevard and Pine Street.

Last month, a motorist challenged his citation by insisting that the yellow light was too short and only remained lit for 3.0 seconds before changing to red and activating the camera. LaserCraft, the private vendor that runs the camera program in return for a cut of the profits, provided the judge with a computer database that asserted the yellow was 3.8 seconds at that location. Bean gave the motorist the benefit of the doubt and watched the video of the alleged violation while counting how long the light stayed yellow.

Tennessee Public Chapter 998 amended TCA 55-8-198 on April 27, 2016, by adding: “Non-payment of this [“notice” or “citation”] cannot adversely affect your credit score or report, driver’s license, and/or automobile insurance rates.”
