This is why I'm a staunch opponent to the red-light cameras. At least for their promoted purpose. Your clip is a perfect example of the kind of accident that would likely result in serious injury - and would have happened even if the intersection had been equipped with a camera. The only difference is you would have received a ticket. Those that intentionally run lights are those that run 'fractional' reds (red for no more than a second) or jump a red light a split-second before they turn green. Neither of those cause any increased risk to cross traffic.
Driving into an intersection that has green for cross traffic, because you don't see the red light, are asleep, or otherwise distracted (or under the influence) happens despite red light cameras. Heck, a cop could have been standing there waving a flag, and you likely would not have seen it.
The potential for these kinds of 'accidents' exists for any human. And it takes modesty and self-deprecation to admit it.
