Subjectivity in applying the law is a huge problem, especially given how corrupt and violent police are. Red light cameras remove police from the equation for that infraction and apply the law evenly. They also scale in a way that police just can't, and that's extremely important for safety.

I live in a city where red light running is an epidemic. Drivers flagrantly just don't stop, and it kills people all the time. Red light cameras - plus actually revoking drivers licenses, and then actually throwing people in jail for driving on suspended licenses - are the only way to fix this.

It's far past time that drivers are no longer immune to consequences for violent, sociopathic behavior.
