FBI documents reveal Las Vegas shooter's anger towards casinos.

New FBI documents reveal that Stephen Paddock, the gunman responsible for the 2017 mass shooting in Las Vegas, was upset over how casinos treated him and other high rollers. Paddock had been banned from three Reno casinos and was reportedly angry that the red-carpet treatment for high rollers seemed to be fading. However, Las Vegas police defended their inconclusive findings and dismissed the importance of the documents, stating that speculating on a motive causes more harm to the victims. Paddock acted alone, killed himself as SWAT officers closed in, and left no note about his motive for the rampage.
