So however much some people might yearn for gun control, it seems unlikely that it would have prevented Cho from achieving his ends. He had substitutes available, he had more than one means available to achieve his ends, and he plotted long enough to hit upon other means — especially since those other means are described in detail on TV, in the newspapers, and on the internet every day.

Why Economists Tend to Oppose Gun Control Laws
[With the doors chained shut even a crude sword would have been a sufficient substitute against the victims disarmed by the bigoted politicians. And as others (Was it Ry?

A few gallons of gasoline and a book of matches would have been rather effective in that environment as well.--Joe]
