Thats were I will have to disagree is (through a lot of work) these criminals don't work hard at all. Criminals are not the ones that have to go through a back ground check because they know they wont pass. There is this thing I think you missed its call the Black Market. Criminals get a hold of any gun they want to. They don't fill out the paper or agree to follow laws. If anything the gov needs to take hold of the Black Market before they start attacking our rights.
