I wouldn't count it as pre-emptive if the assailant was threatening me with a weapon.
Define threatening and weapon, a newspaper can be an effective weapon in the right hands. The subject is at least as complex as the speed camera issue and the ethics of self defence were a common topic of discussion after training sessions.

But I do sympathise with the idea that some one perpetrating a criminal act, whether it be armed robbery or exceeding the posted speed limit, should be out-with the protection of the law.

Again moral issues around the definitions of what constitutes a criminal act abound, what about stealing a loaf of bread for instance? Would a security guard be justified using lethal force against a shop lifter under your rules? For speeding as an example you could say that someone exceeding the speed limit would be assumed to be liable for any incident that occurs, though they would not be automatically be prosecuted for exceeding it if no incident occurs. If the speed limit is set at something just over the 90th percentile then speeding would not be particularly common anyway.
While it is tempting to agree, after all a burglar deserves what they get don't they? It would be scarily easy to end up on the wrong side of the law, particularly if you find that complaining about the law becomes illegal in itself.
