Wailing and lamentations of the wimminfolk is a good one too.
Can you disagree with any of the points raised though?
Well, I can't remember any significant gun restrictions coming out of Columbine, or Aurora. We've had two big SCOTUS cases go our way since Columbine, despite Michael Moore's dancing in the blood of those kids.
Should we be vigilant? Sure. But I'm not predicting the demise of the 2A out of this, or even any significant restrictions. What we can do is watch people reactions, like certain Senators (Edited...it was Joe Manchin, (D) WV) who claimed to be "pro gun".
The shoe is not going to drop. There is no shoe. Dianne Feinstein introduces a new AWB every year, and every year it dies in committee. Gun control is still a political loser, and more so now than after Columbine.
