Unfortunately all of that is still classified but congresspeople who have been briefed have been sufficiently motivated to introduce legislation to investigate further (as Chuck Schumer has recently done in the Senate).
NOPE
Your concern HERE should be that EVIDENCE is being witheld from you and you are the useful idiot.
THAT should be your concern... YOU ARE KEPT STUPID - stand up against that.
EDIT:
GFYS @DANG
I have kvetched to you over this MANY FN times... your BULLSHIT system is I am "posting too fast" when it was SIX FUCKING MINUTES between attempts to post.
You know why I hate reddit? You know why I HATE HN
You are a censorship engine.
When I met with twitter in 2007 they asked me what I thought twitter was, and I stateed it wasa global sentiment engine...
When I met with the googs I told them the same 'everyone thinks your're search - youre an ad based sentiment engine'
Go F U
We've probably cut you more slack than anyone in the history of HN. That doesn't mean it isn't finite, so please stop.
I love you guys - I just want to also keep you square.
So, please allow me to call out dorks being dorks.
If I am an ass then call me out for being an ass, but dont ban me from calling out dorks, or things that HN might disagree.
The part that never adds up to me is the complete lack of concrete evidence in the open (when there is ubiquitous technology for detection in the hands of the public), or the implied astonishing competence of governments and agencies cooperating internationally to keep alien intelligence hidden. We couldn't prevent a pandemic, have lost nuclear weapons and are watching the planet die due to carbon emissions… yet somehow the alien-intelligence-suppression-network works?
