In a new editorial for Newsweek, writer-director David Mamet argued that the individual is the only one qualified to provide his or her own self defense and that one cannot simply rely on the government.

"The police do not exist to protect the individual. They exist to cordon off the crime scene and attempt to apprehend the criminal. We individuals are guaranteed by the Constitution the right to self-defense. This right is not the Government’s to 'award' us. They have never been granted it," Mamet wrote.

In a spirited debate on America Live this afternoon, Megyn Kelly discussed the piece with Fox News contributor Juan Williams and radio host Lars Larson. Williams defended

what President Obama has said about the proposed ban on assault weapons, saying no one wants to take away every gun.

Larson said he believes the ultimate goal of the government is to take away all guns from private hands, starting with the current proposal to ban assault weapons.

"You're basically parroting paranoia," Williams responded. Larson countered by saying Williams was putting out "bad information" by linking the types of weapons listed in Sen. Dianne Feinstein's (D-Calif.) legislation to an "epidemic" of gun murders in the U.S.

Larson said by and large handguns are the main problem in gun murders and those are mostly absent from the bill.
