Who would the USA exit from? I suggest from the federal government. Behold:

There Are Now More Bureaucrats With Guns Than U.S. Marines

The “Militarization of America” report found civilian agencies spent $1.48 billion on guns, ammunition, and military-style equipment between 2006 and 2014. Examples include IRS agents with AR-15s, and EPA bureaucrats wearing camouflage. … Open the Books found there are now over 200,000 non-military federal officers with arrest and firearm authority, surpassing the 182,100 personnel who are actively serving in the U.S. Marines Corps.

I’m sorry (no I’m not), but the government doesn’t get to have temper tantrums and demand that the people should be disarmed while at the same time loading up on the very same arms they say we can’t have.

Whenever there’s a gun control debate, you almost always see the one guy pop up with “Yeah, ok, so what about nukes? Should regular folks be allowed to own nukes? Huh? Should they? Gotcha!” I’ve suggested before that a simple rule of thumb on what arms the civilian populace should not be barred from having is this: I get to buy whatever the internal policing system in the US gets to buy. If the EPA gets to have assault weapons, so do I. If the IRS wants main battle tanks, I should be allowed to buy ’em too. If the Food and Drug Administration gets theater ballistic missiles, so do I. If the Small Business Administration gets weaponized smallpox, then I get the selection of plagues and poxes of my choice.

Don’t want me to have a particular class of weapon, Representative Trigglypants? Then why do *you* get them?
