Rare Tragedies and Policy Changes

Gene Healy applies the post-Virginia Tech "let's not make any wrenching policy changes in reaction to very rare tragedies" logic to the domestic war on terror. A sample:

I'll grant that the future risk of terrorism is more uncertain than the background risk of school shootings. For that reason, I think the risk of terrorism requires a more vigorous policy response than does the risk of school shootings. But it's possible–indeed, likely–that the number of psychotic and potentially murderous young people in the United States with easy access to weapons is much greater than the number of active jihadists in America who have access to weapons or other deadly technology. And the policy responses liberals advocate to deal with the threat of school shootings (policies I totally oppose) are, on the whole, milder and less destructive than those that most right-wingers support to fight terrorism. Would that the Left could be as sober as the Right when it comes to gun policy, and the Right as sober as the Left when it comes to the allegedly existential threat of terrorism.
