Hotel security concerns

Police say Stephen Paddock, the Las Vegas shooter, fired from the 32nd floor of the Mandalay Bay Hotel and Casino, then killed himself in his hotel room. Despite some of the initial reports, the 64-year-old was not on law enforcement's radar and authorities believe he acted alone. 

Paddock was reportedly a high-roller who frequented high end hotels, businesses that have their security on staff to keep an eye on things. Hotel security expert professor Stephen Barth is on the Factor to talk about how something like this could have happened.
