Wow, I am amazed at the people who want you to jump through MORE hoops to get an automatic weapon. Please stop already - its legal to own (in most civilized states) so its done. Look at the track record on civilian ownership of automatic weapons - despite the very sad incident of the 8 year old shooting himself, that could not be prevented by any legislation or 'training'. It was the adults there that should have exercised more common sense.
Taxes of any kind to own seems to be unconstitutional to me to begin with. You start down this path and next thing you know we are back at limitations because certain firearms LOOK scary. You guys are just enabling the gun grabbers. You already have to file paperwork and do some legwork to get automatic weapons - enough already.
