Its troubling to think that there are so many people without brains and they believe in these conspiracy theories ...
Ooops, Donald Trump is President!
And what about the two different types of bullets in the JFK shooting, the solid bullet taken from the Governor and the shattered bullet taken from JFK's head, Oswald's rifle fired solid bullets, the Secret Service weapon fired fragmenting bullets.
As for the 911 conspiracies, don't get me started. There was a good article in Popular Mechanics (I think) which discounted all the 911 conspiracies. No imprint of the plane in the Pentagon walls - yeah it hit the ground short of the pentagon and left an imprint there. The buildings were demolished by thermite explosives cos you could see the explosives blowing out from the building - nope, that was the floors falling and the air compressed between the floors blew outwards taking along with it all sorts of debris. One of the planes which hit the towers was a different type because you couldn't see the windows - yeah you couldn't see the windows because you were looking at the planes at an angle which didn't allow the light to shine in one window and out the other side. The air control radar couldn't detect the incoming panes - air control radar doesn't pick up a reflection of it's outgoing signal, it sets off a transponder on the plane which sends a signal detailing what aircraft it is and high high it is and how fast it's going, all the hijacked aircraft had their transponders turned off. And if the planes flew somewhere else and the military flew drones into the towers and the Pentagon, where are the original planes, passengers and aircrew? What about all the phone calls from the passengers an board the hijacked planes? Oh, I dispair for the future of humanity.
