These silly arguments persists: leave the guns and knives change the human. Sure. There's no difference between an assault weapon and a knife. Sure.
"Jesus" hasn't changed us much in 2000yrs; nor has "the image and likeness of God" over, what, 150,000?  Shall we rely on "evolution" or "grace" and like intelligent beings(?) just wait?
Silber's other "response" to guns management is equivalent to: poor pit bull dogs get a bad break. They're sweet; it's the owner.  If a "poorly trained" pekinese "attacks" it won't get much above my knee and those sharp widdy teeth will leave a mark. The "poorly trained" pit bull however, will get to my throat with a jaw pressure of 250lb that doesn't seem to have a release button.  
So s/he "isn't thinking, s/he is merely 'feeling'?
