Granted USA is not a true Democracy but doesn't that defeat the purpose of a Democracy? Of course I know that you can't have freedom and security these days but should we just start re-labeling the states as a different type of government? I'm by no means an expert however if we are to have freedom to keep our secrets why is it shameful to do so - even if it is "something to hide" is fearful to divulge we should still have that right to make the choice. Correct me if I'm wrong, please, because I'm still very young with politics and as such am still learning a lot about it.
