I'm sure the FBI will subpoena any doctors' records in an attempt to find out why. In the meantime we wait for the press who will use every sly means to get the same info plus any new ones the FBI will not share with us. Interesting how the CNN press was able to get and show us photos of the Mandalay Bay Hotel's shooter's room with all its arsenal. The cops are pissed about this. Good job you press people. The cops are now investigating every cop who entered that room with a body cam or cell phone. Some dude got a couple grand for his generosity. I think there was a court case forbidding any prosecution of any reporter unwilling to reveal their source of information. Confidentiality rules protects first Amendment rights. Hahahaha!!!!
