Good summary...
Definitely SOMEONE is lying...and very probably more than one someone. The big question is why...and there isn't enough evidence available to US to come to a definite conclusion at this point -although some very highly-placed Americans who were/are in a position to have inside info HAVE come to some definite conclusions on this -conclusions at odds with the official story. Without them, it would be just one more conspiracy theory.
The devil(s) would be found in the details, but -once again- too many people on top have no interest in those details coming into the light. All the more reason to keep digging.
They come to conclusions at variance with the official story...while knowingly LYING about the ship's mission.
Until they come clean, as far as I'm concerned, their objections are duly noted and equally duly ignored.
