You are Sisu! They did it all with holograms and explosives, just to get to a CIA office in Building 7? Really? And the families of all those passengers on the four planes are making up the lives of their lost loved-ones? Sigh. Occam's razor. No more to say.
No on Kennedy, btw. Best explanation I saw was on C5 a couple of years ago - a Secret Service officer in the following car accidentally delivered the fatal headshot when he dropped a rifle in the commotion of Oswald's first shots. Absolutely no belief whatsoever that the headshot came from the front at all, much as I loved the late Bill Hicks.
Never said they did, but according to Sisu (not saying this is your argument) they ****ing levelled Manhattan to get to something in an office in Building 7. Utterly implausible.
My 'theory' on a lot of the conspiracies is that the security services run with a fair few of them as they serve to cover up the fact that they're not as good as they like us to beleive.
I make a point of avoiding anywhere that has a grassy knoll, which fortunately seems to be just one street in Dallas.
Still only 3 steel framed buildings in the World to fall into themselves due to fire damage ever . That London block is still standing
