In an attempt to get Judge Kavanaugh to somehow side with the gun-grabbers, Sen Feinstein went back to one of his dissents that noted that semi automatic rifles are in common use all over the country. Sen Feinstein wanted to know what surveys or studies he used to come to this conclusion and argued that if you're not regularly firing your gun, it's not "in use" and therefore subject to restrictions.
Well, Senator, I might point out that your own constituents use theirs regularly in Pasadena at group dinners, and in Washington at baseball games, and in Florida at night clubs. How much more common can usage get? If she really wanted to reduce crime, she would support legislation to forbid firearms ownership to Democrats and Muslims.
