Second Amendment remedies?

I don't know whether the shooter of Rep. Giselle Giffords (D) in Tucson, AZ, had political motives.  I hope not, but given the tenor of the times, it's a question that has to be answered - and soon.

Assassin Jared Loughner could have had a grudge against the federal judge that he did kill outright.  He could simply be crazy and in love with the power of a 9mm Glock with an extended magazine - the power to make him less useless and impotent.

A couple of points:  Open carry of firearms, which is the law in Arizona, utterly failed to deter or end this attack.  Eighteen people were injured, and the shooter was not apparently one of them.  Showdown at the O.K. corral did not turn out to be an effective crime-stopper.

The media is making a big deal about the lack of security for Congresspeople.  As if they didn't know before.  Maybe they're just channelling the ignorance of the public, who don't go to events at which Representatives or Senators show up without any security at all.  During this past election season, I saw my Congressman, Jim McGovern, many times - even at a local Tea Party event - and he never had security.

Update (1/10):  Not only is open carry the law of Arizona.  Concealed carry without a permit of any kind is also the law.

Also, the attack was cut short - not short enough - by unarmed citizens.
