text_2: "Moulton said, ""Background checks have been unequivocally shown to reduce gun violence."" Research has shown background checks to be associated with reduced gun violence, and they’re believed to be a necessary measure to stop guns from falling into the wrong hands. But it hasn’t been scientifically established that background checks alone could reduce violence, separate from a broader system of laws, regulations and enforcement. In short, the scientific literature is fuzzier than Moulton claims, experts said."
