They should tend to their own house before claiming the moral high ground. Take away guns, as the Chinese government has done with its people, and evil men use whatever weapon is at hand.
A series of attacks at schools in China beginning in March 2010 have left 21 dead and about 90 injured. Weapons used in the attacks included knives, a hammer, a cleaver, an axe, and one of those dreaded box-cutters made famous on 9/11. The most recent attack, in which 22 primary school students were injured, occurred on the same day as the shootings in Newtown, Connecticut. Teachers at the school defended themselves and their students — with brooms. (And thank God they did, instead of waiting for police, or this demonic individual might have stabbed more kids.)
My point: It’s a fantasy to believe that disarming the public will put an end to evil acts by evil people. And disarming the American public isn’t likely any time soon — there are too many in circulation already (some of them courtesy of the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives), and too many in the hands of people who shouldn’t have them for law-abiding citizens to give them up.
