The whole "common sense gun control" will sort all this out argument is nothing but political posturing. It's just as much as a lie as when the GOP says that the solution is good guys with guns.
I remember after one of these shootings, I can't remember which one, President Obama lamented that America can't seem to pass "common sense gun control" measures "like the UK and Australia".
In a way, that comment is complete garbage and 100% correct at the same time. It's garbage because in those countries "common sense gun control" means private citizens cant own most guns. Now tell Americans that and see if they regard that as "common sense gun control." That's what I mean about not being honest about the debate. Don't say "Australia did it, why can't we"...tell the truth and say "Yeah, we're going to need your guns. Pretty much all of them." I wonder what would happen if a US politician said that. Hmmmm. In Australia, the so-called buy back program was mandatory. See how that goes over in the US. To say nothing of the fact that the "common sense gun control" that are being held up as models are in countries that don't have a Second Amendment. So why even mention them, unless you've going to suggest repealing part of the Bill or Rights?
On the other hand, he was right in that if politicians are really serious about doing something about this, it's going to take that kind of solution. But of course most politicians in both parties don't have the courage to be honest with Americans and tell them that.
