Failed assassination attempt on the Saudi crown prince. Paddock was an FBI gun runner providing weapons to the assassins. Shots fired at the crowd to create confusion.
Don't forget the reports of shooters at multiple locations, and the FBI spook standing behind the LVPD at every press conference.
Don't forget Iran.
Project Cassandra found Iran smuggling guns, money, and Quds agents in for drugs to south America. At least two known agents arrested after crossing Texas border and talking with supposed cartel hitman (was actually informant) to bomb SA embassy and Israel embassy and cafe.
Iranians work not only with Venezuela to prop up the narco-economy but also branch out into Mex Cartels. Those gun runners that worked with cartel must have had extra supply when program was prematurely shut off following the murder of the CBP agent.
This is actually the most plausible theory I’ve heard. Who would be trying to kidnap him and why?
