In the immediate aftermath of the massacre in Newtown, Conn., I kept hearing people say "this is not the appropriate time to discuss gun control." Baloney. This is the perfect time to discuss it ... and act on it ... while Friday's horror is still fresh in our minds.

A knee-jerk reaction is exactly what we need right now. This may be our last best chance to collectively yell "Enough!" and toughen our gun laws once and for all.

That said, here's where I stand in the debate:
  
I have liberal views on many hot-button issues, but I'm in favor of the Second Amendment. Let me say that again, so it's clear: I'm in FAVOR of the Second Amendment.

I have no problem with people owning guns, but I do see the need for reasonable limitations. A single-shot rifle for hunting? Fine. A hunting shotgun? Sure. A handgun for self and home protection? Absolutely. An AR-15 semiautomatic that can fire 100 rounds in a matter of seconds and kill 20 children? Um, no.

But rather than prattle on, I'll simply offer this: If anyone can make for me a cogent argument about why individual citizens need to own automatic and semiautomatic weapons that are intended for nothing other than killing large numbers of people in a short amount of time, I'll come around to that person's way of thinking and no longer will hold the position that our laws must change.

But I've yet to hear one good reason not to ban these tools of destruction and seize as many as possible that already are in circulation, and I doubt I ever will.

We know those weapons aren't used for hunting. We know they're not small and compact, like weapons needed for personal protection. And we know, from our recent history, that they are the weapons of choice for deranged people bent on carrying out mass murder.

And that, quite simply, has to stop.
