G&A magazine has published a comparative ranking of the states with respect to their various CCW laws. Not surprisingly D.C. finishes last with a score of zero. It's also the only place to pull down this number. CA, HI, NJ, and NY finish out the bottom five.
I put the scores into a spreadsheet to see how the numbers broke out and while the rankings are not without their flaws, the question to be answered here is probably "Compared to what?".
The graph suggests that while 70 is indeed better than 68, the big drop happens at 60. If your state is doing better than that, you're on the happy side of the list.
H/T to No Lawyers - Only Guns And Money for the lead.
