Chris Rock has a novel idea for gun background checks.
"The gun lobby always says, well, people need the right to protect their property," he told TheWrap. "Every mass shooting is done by a guy who lives with his mother. I honestly believe you should have to have a mortgage to buy a gun. No one with a mortgage has ever gone on a killing spree."

Rock has made the point before that the suspects in mass shootings tend not to own property. But he went a step further at the Television Critics Association winter press tour Wednesday, saying he seriously believes a mortgage should be a requirement for gun ownership.
He was speaking during a panel about FX's "Totally Biased With W. Kamau Bell," which he executive produces.
Rock made a joke several years ago that gun deaths could be cut down if bullets cost $5,000. Lawmakers are starting to see his logic: Democratic Sen. Richard Blumenthal has announced that he will introduce legislation to require background checks to buy ammunition.
