The left takes advantage of every opportunity it gets to vilify gun owners. And the murders at Newtown, CT, have presented them with a crisis they don't want to waste.
Gun groups are probably already organized and ready to combat the false narratives that will surely come forth about guns.
The NRA gets a lot of heat for its aggressive defense of 2nd amendment rights. Even gun owners get tired of it at times. I was an NRA member some time ago, but their relentless pandering for money got very annoying. However, they have provided a service to gun owners by attacking even the slightest attempt to restrict gun rights. They aren't the only ones doing it, and their work along with other pro-gun groups has paid off.
To see what would have happened had defenders of gun rights not been so aggressive look at cigarette smokers. The attack on smoking started out with just a few innocuous rules. Smokers said, "OK, we can live with that." Then came another, then another. And before long smoking was banned in airplanes, rental cars, office buildings, bars and seemingly everywhere. The war on smokers was over and smokers lost. Now you see small groups of them, outcast, shivering on cold stoops, smoke wafting about their heads.
The camel stuck his nose under the smokers' tent and upended the whole thing.
Oh, that's different, you say, because smoking is bad for you. The same argument is made about guns, and without aggressive resistance, expect the same result.
Addendum: Watch Louie Gohmert explain the need for 2nd amendment protection to Chris Wallace on 12/16/12.
