During an interview with Sen. Tammy Duckworth (D-IL) on Thursday’s broadcast of MSNBC’s “All In,” host Chris Hayes stated that “Meaningfully reducing gun violence in America would require some pretty significant changes to the policy landscape.” And that while things like expanding background checks would make a difference in gun violence, “the people who oppose further legislation understand that” as “the camel's nose under the tent. Like, they get that that's the first opening salvo to try to get more and so they don't want to do any of it.”
