There are a couple of questions I would love to ask these distinguished and intelligent gentlemen. (1) You have singled out the tool of choice for the perpetrators of this violence you speak of, but can you describe the root causes of this violence? (2) Would the loss or reduction of the deterrent affect, provided by an armed population, be far worse than a reduction of gun related violence? Isn't the threat of tyranny far greater that the present weakness in our social fabric? (3)Wouldn't it be far wiser for government to examine why Americans are violent...and use guns? (hint:drug prohibition)And shouldn't we use our resources to reduce the sociopath tendencies of many Americans.....And not focus on a tool that the large majority of Americans posses and use legally...and with care?
I think the thing you miss is that these people are all for tyranny as long as they are in charge.
