Rated Mostly True, but they ignore the primary reason: Because most of the denied background checks are false positives, or denials of Constitutional Rights to elegible people.
Before Congress enacts any new gun control laws, the nation’s law enforcement officers and courts should better enforce the regulations they have on the books now, according to U.S. Sen. Kelly Ayotte.
In a meeting with the Telegraph editorial board, New Hampshire’s junior senator took aim last month at the national background check system, which does not go far enough prosecuting those who illegally try to obtain weapons, she said.
“Of approximately 80,000 in 2012 that were denied (a gun) because of a background check … only 44 people were prosecuted for that,” Ayotte said during the February 19 meeting.

It has nothing to do with the law, or the constitution. It’s just another technique to prevent people from owning guns.
