The truth is, in the aftermath of the Vegas tragedy we should not look to the government and politicians to "fix" things.
But Paddock may have been scouting other locations, including the Life is Beautiful music festival, which was held in Las Vegas the weekend before Sunday's attack.
The attacker, identified as 64-year-old Stephen Paddock, of Mesquite, broke two windows on the 32nd floor of Mandalay Bay and unleashed a 10-minute barrage of bullets at the Route 91 Harvest music festival across the street.

Newton told reporter Bill Whitaker recalled how they entered the room amid the flashing lights of a fire alarm set off by an explosive used to blow through the door. And thousands of people turned out to honor him. He vowed in his weekly address released Friday that victims would "never be forgotten".
