Red light camera would not have stopped you getting tboned. In fact red light cameras have been shown to increase accidents where they are used.
Just like more gun laws don’t stop bad people illegally using them.
Red light crashers have a habit of repeating the same. The guy who flew through crossing well after red light would get lots of tickets and that might alter his behavior eventually.
I watch that show “See no evil” where many crimes are solved due to camera’s observing street activity. Frankly we are all safer with more public camera’s. This is not big government trying to confiscate your guns or money. The revenue from traffic camera’s is minuscule compared to property taxes, income taxes, utility taxes, auto licensing taxes, gasoline taxes, sales taxes, etc.
