From an 2011 interview with PBS's Jim Lehrer:
JIM LEHRER: New subject, Mr. Vice President.Say what you will about Biden, he hasn't shied away from his support of gun control. So it makes one wonder what it is about anti-gun politicians and their fascination with violent rhetoric. Look at what he had to say this afternoon at a campaign stop in Naples, Florida.
In light of the Tucson tragedy, are you in favor of federal legislation that would ban the sale of these multiround cartridges, holders?
JOE BIDEN: Jim, you may remember, in the old days, when I had some real power...
JIM LEHRER: Oh, yes.
JOE BIDEN: I was chairman of the Judiciary Committee.
JOE BIDEN: I'm the guy that first passed and wrote the assault-weapons ban and -- and also tried to pass legislation relative to the size of magazines, that is the -- those clips that hold all the bullets that get shoved up into the rifle.
JIM LEHRER: The 31 -- those 31 rounds.
JOE BIDEN: Yes. And there's all kinds of them of various...
JIM LEHRER: Sure. Sure.
JOE BIDEN: So -- so, I, as a senator, and I, as an elected official, have been on record as supporting -- and we did originally have an assault-weapons ban in place.
Vice President Biden lit into Paul Ryan with a violent analogy during his campaign stop Thursday in Las Vegas.The Republicans have bullets aimed at you? What is with this nonsense? Doe Biden make this stuff up off the cuff or does he actually have someone writing it for him? Is he trying to emulate President Cooler Than Thou who promised to bring a gun to a knife fight?
"Ryan has written a book called 'The Young Guns' with two other members of the House ... Republican leaders in the House," the vice president said. "You had, unfortunately, the bullets are aimed at you."
As to bullets "aimed at you", while there has been some research on bullets that can alter their direction in flight, bullets don't aim themselves. You aim the gun and the bullet goes where it is directed. Even a buffoon like Biden ought to realize that.
