Former Vice President Joe Biden talked about smart guns with biometric measures during night two of the Democratic Presidential candidates’ debate, nationally televised last Thursday.

"We should have smart guns. No gun should be able to be sold unless your biometric measure could pull that trigger,” Biden said. “It’s within our right to do that. We can do that. Our enemy is the gun manufacturers, not the NRA.  I would buy back those weapons. We already started talking about that. We tried to get it done. I think it can be done. It should be demanded that we do it and that’s a good expenditure of money. I’m the only person that’s beaten the NRA nationally. I’m the guy that got the Brady Bill passed, the background checks. Number two, we increased that background check during the Obama/Biden Administration. I’m also the only guy that got ‘assault weapons’ banned. Banned. And the number of clips in a gun banned."

California Rep. Eric Swalwell said he was the only candidate asking for a “ban and buy-back of every assault weapon.”

Bernie Sanders said, “We have a gun crisis. In 1988, when it wasn’t popular, I ran on a platform of banning assault weapons. We need comprehension gun legislation. I believed in 1988 and I believe today… assault weapons are assault weapons of the military, and they should not be on the streets of America.”

Kamala Harris said, “The problem is Congress does not have the courage to act," adding that if she were elected president,“I will give Congress 100 days to pull their act together,” and “take executive action and put in place most comprehensive background check policy we’ve had.”
