“[O]nly 2.5 percent of the population can legally carry a firearm,” the Times of Israel reported in 2012. “But those who are licensed to carry a weapon have proved capable of acting swiftly and effectively time and again to neutralize attackers during acts of terrorism.”
Armed civilians have often stopped terror attacks.
I’d note that more than 2.5% of the US population can legally carry firearms. If it works in Israel, why would it suddenly not work here? No, if you’re an American you’re apparently more likely to shoot yourself with it.
