CONSIDERAD dos escenarios, propone Eugene Volokh:

1. An armed madman comes to a place and starts shooting people. None of the people who's around is armed.

2. An armed madman comes to a place and starts shooting people. Several (say, five) people in the vicinity are armed.

Which madman is more likely to be stopped quicker — the one who outguns everyone else 1-0, or the one who is outgunned 5-1?

If this weren't a madman but Jack Bauer — or even an average highly trained soldier — the five may well be unable to stop the one. But otherwise, the odds would seem to be more against the madman in situation 2 rather than 1, no?

No-one can prove anything, of course. Maybe the five would be the first to be shot. Maybe they'd run away. Maybe they wouldn't be around. Maybe they'd shoot and miss. Still, if you had to bet, which would you bet would be the worse scenario for the madman, and the better one for his victims?

Now of course if arming the five people for the extremely rare situation when they'll need to stop a madman will end up causing more harm than good in the much more common situations when there's no madman around, that might be a bad tradeoff. That is the argument I've heard against letting students possess weapons on-campus: They're young, they drink a lot, they'll start shooting when they get into a hot argument in class or at a debate. I'm not sure that's right, but let's say it is.

What, though, is the argument against allowing professors and other university staff to possess weapons, if they choose?
