LOL, Lefties are always late to the war...
In 1986, there were only 9 states that had "shall issue" laws for concealed-carry permits, and 15 states utterly forbade the practice... the NRA has been putting up a good fight since the 1980's.
In 2006, there were 39 states that were "shall issue" or unrestricted, and only 2 that do not issue concealed carry permits under any circumstances.
(EXPLANATION: "May Issue" laws said that if you apply for a permit, the local authority MIGHT allow you to get the permit... but he was not required to give you one. He also would not have to give any valid reason for the refusal. "Shall issue" laws mean that, unless you have a previous violent felony or a current psychological disorder, the locals MUST issue you the permit. "Unrestricted" means that you can carry concealed without a permit.)
Strange that the US saw a decrease in violent crime rates starting in the late 1980's. Purely a coincidence, I'm sure.
I would love to see more Green States crops up... It's the Constitutional thing to do. ;-)
