Lots of info from NHTSA [1]. Like many complex things, it's tricky. "While the presence of a red light camera system has reflected increased numbers of lower impact rear end crashes at intersections where the systems are installed resulting from drivers stopping for the red light, research has also found a reduction in more dangerous offset and right angle crashes at intersections with red light cameras".

In general it seems like a win to me but if you get into technicalities then yes, some research has shown more low-impact rear end collisions. They go on to say "Additional studies may provide greater insight into whether or not such crashes persist where the technology is in place for longer periods of time. The effect of warning signs, public education, and familiarity with the presence of the system in the fullness of time is not clear."

Plus that way it only affects a speeder and a tailgater, not a speeder and someone else. Lose lose win but in a fairer kind of way.
