I don't remember where I read it, but I saw figure that approximately 50% of the Ar's are privately owned by law enforcement personnel.
But no one seems to know exactly how many ARs are out there. Numbers range from 5 to 10 million, and that can't account for unfinished receivers made into working rifles, because those were not FFL transferred and not weapons when sold.
If people paid cash, the government can only estimate what is out there, who might have it, and how much ammo they have for it.
But the bottom line is this. THe 2nd Amendment does not grant anyone a Right (in fact, the Constitution doesn't grant any Rights). The COnstitution grants limited powers to the Federal Government, and limits those powers. The Second Amendment merely recognizes the Right of the People to Keep and Bear Arms, to keep the Militia (Army, in 1780s English) well controlled (regulated) so it could not be used to impose tyranny on The People.
An Army is necessary to the security of a Free State, but so is controlling that Army, which is exactly what the predicate clause is about. The Power, however, is to remain with The People, and Government is to keep its grubby legislating fingers off the Right.
The Second Amendment is not a grant of a Right, but a specific limitation of the power of the Government.
Every one of those SOBs up there in DC swore an oath,
In the House:
“I, AB, do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation or purpose of evasion, and that I will well and faithfully discharge the duties of the office on which I am about to enter. So help me God.â€
In the Senate:
I do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter: So help me God.
To even propose legislation encumbering the Second Amendment Rights of American Citizens, these people are in violation of their oaths of office, and what's more, in violation (prima facie) of 18 U.S. Code § 241, conspiring to deprive Americans of their Civil Rights.
Where's the DOJ on this one?
