The British admire grace under pressure. Americans aren’t so big into that. Mass hysteria is more our style. We’re rushing out to buy handguns and rifles in record-breaking numbers. The odds that someone with a handgun will be in the right place at the right time to kill a terrorist are actually pretty small. What’s more likely is that many of these newly-purchased weapons will eventually be involved in an accidental shooting, a suicide, or a domestic dispute. Some will find their way into the black market. One thing for sure, any would-be terrorists will have no problem buying weapons.
