Okay, you can google around for studies. There are many. But I found this interesting (from Wikipedia):

A 2004 Texas Transportation Institute study found, "crashes decrease with an increase in yellow interval duration and a reduction in speed limit." After 1.0 second was added to the yellow signal timing at test intersections, accidents dropped by 35 to 40%. This compares with a 6.4% reduction for "area-wide officer enforcement of intersection traffic control devices... during the time of the enforcement activity" [7].

So, instead of adding cameras, why not just add a second to the yellow light? Oh, right, that doesn't bring in money.
