What If 20% of the Adults in That Colorado Theater Had Been Armed and Trained?

From Gary North:

I have a question.

If 20% of the adults in that Colorado theater had been armed with a handgun and trained in its use, how many people would have died in addition to the shooter?
I think the answer is clear: fewer.

The reason why so many died is that 99% of the people in that theater were unarmed. There was only one exception.

I offer a proposition:

"Armed and dangerous" is an inescapable concept. There is no such thing as "unarmed and safe." There is only the question of which person or group is armed and dangerous.
It would have been far better if 100% of the adults in that theater had been armed and trained. But we must be reasonable in our assumptions. We cannot expect 100% of any large group to get trained in the use of a handgun. But 20% is reasonable.
