From Fox News:

BILL O’REILLY, HOST: “Impact Segment” tonight as we reported last night the far- left is trying to use the Colorado movie massacre to promote gun control. The brother of a young woman murdered by James Holmes was confronted by that last night.

MSNBC HOST: Do you feel compelled to push for tighter gun laws?

JORDAN GHAWI, BROTHER OF JESSICA GHAWI: Well, here’s the thing. We can try to politicize this and make some sort of polarizing debate and make this a tenet of the election. But that’s not what we are here to do right now. We are here to celebrate the lives of the victims that have been lost. If somebody’s to do harm to somebody they are going to find a way to do it.

O’REILLY: Then of course that’s true. But it also makes sense for Congress to pass a new law that requires the sale of all heavy weapons to be reported to the FBI. In this age of terrorism, that law is badly needed.

Joining us now from Washington, Congressman Jason Chaffetz who disagrees. Where am I going wrong here, Congressman?

REP. JASON CHAFFETZ, (R) UTAH: Bill, giving the FBI a master list of everybody who owns weapons in this country is not the right direction.

O’REILLY: Now do you think you just categorize what I said accurately everybody who owns weapons. That’s not what I said and you know it?

I said, heavy weapons, all right. Mortars, howitzer’s machine guns. In this age of terrorism, if you do a flight school, the FBI is alerted. But you can buy a machine gun and the FBI doesn’t know. And you think that’s responsible?

CHAFFETZ: No that — well, first of all, I don’t think that’s absolutely not true. If you buy a fully automatic weapon, you have to go get a tax certificate from the Bureau of Alcohol, Tobacco and Firearms in order to do that. You have to pass a fingerprint background check.

O’REILLY: Have you ever been to a gun show, Congressman? Have you ever been in a gun show?

CHAFFETZ: Yes, I have.

O’REILLY: You know, you can buy any weapon you want there and there’s no reporting anyway; you can walk right out there.

O’REILLY: You can buy an AK-47 in this country and no federal agency will know you by it. And as the guy in Colorado proved, you can buy a mass amount of ammunition on the net, ok, and nobody is reported.

Good grief.  The ignorance is astounding, but idoicy is brazen ignorance, and that’s what is on display here.  We’ve covered this before, but the Firearm Owner’s Protection Act of 1986 banned the sale of machine guns manufactured after the date of enactment to civilians, inflating the cost of fully automatic weapons then in circulation to $10,000 or more (far beyond their actual worth).  For most people, it is cost prohibitive to own a fully automatic weapon, and purchase of one requires registration and approval with the ATF and local law enforcement (oftentimes not granted).

You cannot own a fully automatic weapon without ATF approval, a tax stamp and registration (as well as local LEO approval).  A fully automatic weapon has not been used in an illegal shooting in the U.S.  in nearly a century.  Even purchase of a semi-automatic weapon requires a background check and completion of ATF form 4473.  This applies as well to gun shows.

To be sure, individuals can sell weapons to other individuals without going through a Federal Firearms License in many states, but this is true regardless of whether the circumstances of the sale include being at a gun show.  And selling to individuals who cannot otherwise own a weapon is still illegal, regardless of whether you are an FFL or a non-licensed individual.  To say that people can have illegal things because they can break the law is a tautology, and doesn’t advance the discussion.  It only makes people more ignorant.

O’Reilly goes on to mention howitzers.  Yes, howitzers.  I’m not sure what color the sky is in O’Reilly’s world, but he has the same knee jerk reaction to guns that most Northeastern elites do (e.g., Chris Christie).  The offensive part in this case is his transmission of ignorance to his viewers.  Be aware – concerning guns, Bill O’Reilly is an idiot.

UPDATE: Thanks to Glenn for the attention!
