The Constitution says that the federal government can't restrict your right to keep and bear arms.
It doesn't say that the government can't make it illegal to sell guns.
'cause, you know, the area around gun stores is just more dangerous. Kinda like the laws banning fast food restaurants in poor areas of town.
Which also is meaningless in this post-Constitutional country. What, Scalia gonna waddle down and tell the sherriff to knock it off?
