Do they ask you about your FB/Twitter account or do they already know them?
You may not ever have experienced what I've described, but it happens every single day, time and again. You can find others' reports if you care to look for yourself .. my anecdote only has relevance if it serves to make you, an American citizen, truly contemplate what you have allowed to occur in your name. The security nightmare is real for a lot of people.
BTW, I left you the, surprisingly hard(took me 3 minutes) to find, evidence you asked in the other comment.
A 5 minute search on the Internet would be... enough?
As if all similar stories are part of some global conspiracy?
Like... you only know how good, efficient and super cool the people at the TSA are?
Really?
Laura Poitras is an American citizen too. Is she credible enough for you? Can you tell me what are her thoughts on the TSA?
No? Do you even care? If you do care, then put the effort to learn what is already accessible to you. Otherwise what's the point in engaging in discussions with comments "oh yeah you read it on the Internet derp derp"

EDIT: it seems, when facts come in, downvotes are cast! Ouch. It burns
My anecdote - I'm Australian, lived in USA for decades, moved to Europe after 9/11. Every time I visit the USA it is an hours-long ordeal to explain, in fine detail, why I have the views I have, why I follow Snowden, why I participate in European hacker cultures, why my laptop is covered in security-conference-related stickers, etc. etc. During this process there is always the implied threat of imprisonment without due process. All my stuff is gone through. They find nothing, because I am not a threat in any way, other than that I freely associate with those aspects of society and culture which 'the mainstream' find mysterious, confusing, and scary.
So, I don't go to the USA much. Its about as much fun to get there as driving into a brick wall.
