FBI data released to the AP reveals that background checks blocked nearly twice as many gun sales in 2020 as in the year before, largely tracking with the record-setting surge in sales that took hold along with the coronavirus pandemic and has continued into this year. Nearly half the denied sales were for people with felony convictions.After a year of pandemic lockdowns, mass shootings are back, but the guns never went away. As the U.S. inches toward a post-pandemic future, guns are arguably more present in the American psyche and more deeply embedded in American discourse than ever before.
