Several years ago three terrorists entered a restaurant in Israel and opened fire, intending to commit the same type of atrocity as recently occurred in Killeen, Texas. Within seconds, two of the terrorists were dead. The wounded survivor complained he had not been told that the Israelis were allowed to carry guns.The tragic loss of innocent lives in Texas is the direct result of useless gun laws that deny our citizens the right of self-defense. Now Congress, in its infinite idiocy, is piling on another batch of illegal restrictions of our Constitutional rights. We need less congressional hypocrisy, not more absurd gun laws.
