This one was definitely a CIA plot
My hunch is a McVeigh type terorist act with Phillipino Al Qaeda as sponsors. Except , like with McVeigh, no one wants to blame the islamists.
At the time the Philippines was being helped by the US to suppress the ISIS gangs taking over that whole city in the Philippines.
Paddock who had a Philippino islamic girlfriend attacked on October 1, 2017. What was happening then to islamists in the Philippines eight before that in the summer?
I just googled it. https://youtu.be/O16JP0YRKv4
Philippino offensive against ISIL.
