I agree with "don't run red lights" and "don't drive like a jerk" in general, however, my perception (as someone who lives near DC) is that traffic cameras are not at all intended to make the roads any safer, they are designed as "gotcha" devices to punish people who are driving in a normal everyday manner e.g. by putting speed cameras on a road with artificially low speed limits or putting RLCs at intersections that have yellow intervals shorter than they ought to be (and not subjectively, I'm talking about official guidelines here.) So while I'm decidedly anti-driving like a douche, I'm also anti-camera enforcement as well.
Some light bedtime reading here - an old document but sadly things haven't changed much (the state of Virginia being the notable exception)
