Was able to find FLA and Alabama on state .gov pages. Alabama just gave a total, while FLA broke out firearms and various non firearms, but not type of firearm, i.e. Handgun/shotgun/rifle/unknown firearm. Getting those put in now.
The three missing states, FL, AL, and AR are in using their state reports. Also added the three restrictive law categories for AWB, May Issue, and Permit to Purchase. Here's the new link.
Edit: If someone who knows how wants to download it, and add the standard deviation stuff talked about earlier, they can PM me for my email address and I'll put that version back up.
