Common sense gun laws to lessen the likelihood of mass murders would be welcome. I was in Vegas, and at the Mandalay Bay casino, when the shooting started Sunday night. Even though I was never in imminent danger, I didn't know it at the time and have never been as frightened. Insanity is allowing the same events to occur over and over again without taking action. The United States is alone in the world in this regard involving guns, and the NRA and GOP absolutely have the blood of victims on their hands.
