No, the problem at Sandy Hook wasn't the lack of men
Megan McArdle thinks that gun-control measures wouldn't accomplish much but that training kids to run at a shooter instead of away might. That's a weird payoff at the end of a 4,500-word post, but it's not as offensive as Charlotte Allen's argument:
There was not a single adult male on the school premises when the shooting occurred. . . . Think of what Sandy Hook might have been like if a couple of male teachers who had played high-school football, or even some of the huskier 12-year-old boys, had converged on Lanza.
Well, he probably would have shot them dead. Just like he killed principal Dawn Hochsprung, who (as Allen half-acknowledges in a side point) acted heroically in trying to stop Lanza. Unmentioned by Allen: the several other Sandy Hook faculty and staff members who died not running for their lives but actively trying to protect students from the shooter.
