Also laws that makes it too expensive for poor people to own guns could be construed as unconstitutional. Not sure you can just say AR rifles ok but it takes 500.00 to do the background check and you have to do it ever yr etc. That will take poor people out of the loop and be a defacto rich guys can have them poor can't.
Also how long do you want to throw people in prison for violating things like failing to get your safety class renewed, or having a clip that holds 20 instead of 10 etc. Do we want prison time for them, just a fine and a slap on the wrist? what?
