I don't care much for the official explanation either. It is likely to conceal a lot of things for national security reasons obviously, but also, I doubt Hardwork has actually read the thing.
If you haven't, here, start reading, make your points from that instead of arguing from ignorance which is what you have been doing seeing as you are sourcing and citing incorrectly for the most part and likely never got trained in how to effectively research and opted for the youtube thing as you have shown to be doing.
so, read this:

That is the report, the whole thing, free of charge.
Dissect it and then come and point out those holes for us so we can see where you're coming from and continue from there.
NOBODY is going to be persuaded by anyone who's soul source appears to be youtube videos and college kids accounts of half remembered things they were not present for in any capacity of true understanding. :)
