We can’t just throw our hands up and say, “Criminals will always get guns.” That’s absurd — we don’t give up in the war on terror because “terrorists will always get bombs.”
In the WoT we don't focus on trying to prevent terrorist from getting explosives. Terrorists will always be able to get bombs. Instead we kill or imprison terrorists. Dead terrorist don't make bombs. And dead criminals won't shoot folks. A cheap way of having more dead criminals is to promote the arming of the law-qabiding citizens. and empowering them to legally defend themselves.
