I expect worse than that. It will be open season on the second amendment.
You know the left is going to do its damnedest to reap a political harvest from of Giffords’ shooting. Gun control, web IDs, and just cheap propaganda seem very predictable right now.
They realize that even with a national furor over this incident, the drastic step of full ban or national ID would be impossible. So, they'll opt for the incrementalism - ban on extended mags, then mags that protrude, mags more than 5 cartridges, then down to 3, etc.... If he recently purchased the weapon, you may see a simultaneous call for extended waiting periods, etc.......It is their way.
