It only makes sense ...

.
... if you're the government:

The U.S. government unconstitutionally prohibits people who hold state-issued medical marijuana cards from buying guns, says a medical technician who was not allowed to buy a gun for self-defense.

S. Rowan Wilson sued the U.S. attorney general and the Bureau of Alcohol, Tobacco, Firearms and Explosives in Federal Court, challenging Section 922(g)(3) of the federal criminal code, which "prohibits law-abiding adults who have obtained medical marijuana cards pursuant to state law from lawfully purchasing what the Supreme Court has called 'the quintessential self-defense weapon' and 'the most popular weapon chosen by Americans for self-defense in the home,'" (citing District of Columbia v Heller, 554 U.S. 570, 128 S. Ct. at 2818.)

I know that most of the Elmer Fudds in the NRA won't agree with me, but if a state authorizes the use of marijuana under certain conditions, the feds really don't have a leg to stand on as far as banning things.

I also understand that the way the feds read the constitution is nothing at all like the way I read the constitution.

Oh, to live in a society in which citizens are held accountable for their actions, not the things they own ...
