FILE - In this Sunday, Oct. 1, 2017 file photo, police officers stand along the Las Vegas Strip near the Mandalay Bay resort and casino during a shooting at a country music festival, in Las Vegas. Jay Purves and his colleagues at a private security firm manning the Route 91 Harvest festival Sunday night were a force of 200 unarmed first responders who lifted people over barriers, hid them behind pillars and under the stage, and funneled them to exits amid the panic. The guards are the first ones people inside an event go to when there is a problem.
