Catch 22. Worth remembering that this is a secret program, governed by "secret law", run by secret police, with strong penalties (including international manhunts) for those who expose abuses. You want us to rattle off incidents? Then start by giving whistleblowers immunity to actually report abuses.
The "secret law" part is the one that really floors me. The FISA court orders are themselves secret. Ignorance of the law is no excuse. But knowledge of secret law is itself a crime.
America is now watched by secret police.
