Then why not fess up? Say what they know ISN'T true? Your reply makes no sense - and not many "truthers" suggest the "government" is to blame - quite opposite - they suggest the people and powers who CONTROL the government are behind this. An important distinction.
An inside job could be the gov or as you say those behind it, but no persuasive case has been made that either was involved in concocting the deed.
The "important distinction" you refer to is one the 'truthers' consistently miss, that lies and incompetence don't add up to culpability.
OK, then why not release all those confiscated video tapes?
My mind is not for rent to any God or Government, There's no hope for your discontent - the changes are permanent!
