"But, the NSA will probably have a copy of it before you logout out of
Dropbox . . . "

Of course. The probably got a copy of it beforehand.

You know eventually someone is going to sue the government over this, and by someone I mean a corporation. They will sue for damages for the expenses incurred transmitting sensitive information via courier on disk or thumbdrives and **** because it is not yet copyrighted.

They will most likely win, as it is illegal to use any encryption the US government cannot break, plus the fact the NSA employees have misused their power to stalk Women and **** like that.

Doubt it ? Hey, this is the USA. Wait until they start suing from other countries in world courts. You think it ain't gonna happen you just keep on thinking that.

What's more, Narus and Verint are largely controlled by foreign entities not sworn to the US government for secrecy, just like those folks who handle your credit and medical records in India and elsewhere.
