Paddock was Gunrunner

“The LVMPD knows the motive behind the attack, but the FBI will not allow us to release the motive because it implicates the FBI in illegal arms deals and supplying arms to ISIS terrorists within U.S. borders.”
“Stephen Paddock was an undercover FBI agent who participated in multiple illegal arms deals in the Las Vegas area in a gun running entrapment scheme similar to Fast and Furious. Paddock thought he was engaging in another routine arms transfer, but ISIS operatives who were going to meet him learned about the entrapment scheme and Paddock’s true identity. They killed him and carried out the massacre, and then fled the scene.”
The email concluded that people within the police department are “disgusted” and are “pushing for this information to be released to the public.”
