When incompetent authorities fuck up, conspiracy theories come crawling out of the woodwork.
He’s right. There is no communication between the FBI, local law enforcement, and hotel security. The whole thing is fucked because Mandalay Bay doesn’t want liability and they know lawsuits are coming. Paddock entered the hotel and was able to sneak dozens of weapons and thousands of rounds of ammo into his room. If his behavior appeared suspicious, no one felt comfortable asking him about the multiple bags he kept bringing in.
They should just admit they got totally caught by surprise by a mentally-deranged wackjob with a mission/agenda he took to his grave.
