pretty simple really:
As to your suggestions in reply to Jeff's question - let's entertain those for a while.
For each, please explain the desired end state, specifically articulate what you'd do to implement the suggestion, and tell me how that implementation would achieve the desired end state.
Registration. If the point is to keep guns out of the hands of folks that shouldn't have them, how else to do it? BTW - it's working in California through ammo purchases. Folks are being flagged and having guns removed.
Expanded mental health care - should be self explanatory. identify the Lanza's before we all know their name. See item #1
Lethality. Reduce absolute lethality. You don't have the right for an RPG. Why is that?
Liability. Get folks to lock up their toys. Reduce accidental deaths - especially kids.
Taxes - you gotta pay for this shit somehow. I suggest a user-based tax.
Of course, the whole thread is moot. How many times will we kick this around? Certain people will nibble at the edges and talk about how to make the proposals better, or just other, better proposals. Others will wonder why we try to do anything as there 300 millions guns on the streets and the best way to combat gun violence with more guns. And then there will be purists who want their RPGs.
Who's asked for RPGs?
Btw - go back and read what You wrote re registration. You said "people" were getting flagged. That's through background checks. Has nothing to do with registration of the gun?
