Agreed, mostly. But without SOME secrecy, a government can't function.
Imagine if the US became 100% transparent. You could listen to the president's phone calls, watch military strategy in real time, etc. Unless the government's enemies (its proper ones - criminals, opposing armies, etc) were likewise transparent, which they wouldn't be, Uncle Sam would basically be doomed to be beaten by them. Like if only one poker player had to show his cards in a game - he'd lose.
Just saying there are limits to the good that transparency can do.
When did we start thinking that we can have democracy and freedom without accountability?
It isn't about conspiracy theories. It's just common sense that some people will abuse their power if they can't be held accountable.
