It started bigtime (from what I remember, I'd bet it's been going on forever, though) with the jfk whack and the magic bullet lone nut assain theory, completely ignoring all sorts of peoples immediate eyewitness testimony, including the crowd pointing to the grassy knoll. It was so wildly successful that they have used it to this day. Some notable whoppers include the gulf of tonkin attack which "justified" the nam war, the mass millions of atrocities fantasy that "justified" the kosovo invasion and pounding serbia, to the twa800 magic exploding center fuel tank and the ability of aeroplanes to climb thousands of feet vertically while at the same time defying the laws of gravity and physics when they are basically unpowered and in large not-any-longer-aerodynamic chunks.
Now we got this one, they are ignoring the civilian eyewitnesses that there was an explosion ahead of any pieces of plane falling off, and they are still mysteriously silent on the eyewitness testimony of the quite nearby military helicopter crew, and the fighter jet pilot. They can order them to remain silent, and they follow orders. So,it's like-why bother giving the government/cops/whomever authority figure a statement if you are an eyewitness to anything, it'll be ignored or you will politely be called a liar or delusional. You might even be accused yourself, like they tried to pin the olympic park bombing in atlanta on richard jewell.
I think it's better to tell them to get stuffed if they even ask you a question. Tell them you'll give your statement to the press and to your own lawyer, and that's it, and only if you even feel like it, or unless you are called as a witness to court, and they'll find out what you saw right then, not before. The only eyewitness testimony "they" believe is anonymous snitch phone calls, now THOSE they universally believe (especially when it's another "governmental employee" calling from a payphone down the street who's the anonymous snitch).
You people are so predictable. By the way, 41 people say that the shots came from the Book Depository. 2 people on the Grassy Knoll said the shots came from there and Zapruder wasn't one of them.
It would be easier for the government to say that terrorists did it rather than thinking that the next plane you get on, parts are going to fall off.
