Americans worry about terrorists infiltrating our borders from offshore and wreaking havoc. But last week’s mall shooting (as well as Church shootings in Colorado) again reinforces how vulnerable we are to garden variety All-American nut jobs who get their hands on guns and spread easy carnage, making for lurid coverage on CNN and FOX. And as we know in the gun-friendly USA anybody from mental cases to you or me can find or buy an AK47 and ammo clips to do ugly deeds without much trouble. So last March it was Virginia Tech, last week it was Omaha, a few years ago Columbine. No one wants to deal with the gun menace so more indiscriminate mass killings will certainly happen like the West Roads mall tragedy. And if mental cases can spray gun fire around a mall, well how easy would it be for a terrorist or group of terrorists? Forget about dirty bombs. And let’s face it, mall owners can do very little to stop people of any stripe who want to commit mayhem. The cars with yellow lights patrolling the parking lots won’t stop them. Will shoppers put up with metal detectors at mall entrances?
