I see things like this and it makes me hopeful. Hopeful that there might come a day when those Americans who so cherish their constitutionally-mandated ability to keep and bear arms nonetheless line up to get rid of their guns, fed up at last with the pervasive, random, culturally destructive power of firearms.
Well meaning granola-chewing liberals with buttons and placards can never convince these people, government will have to make good on Charlton Heston's "cold dead hands" taunt to end the problem by state action. It must come from within.
