'Sorry, I've forgotten my decryption password' is contempt of court, pal – US appeal judges
Found on The Register on Monday, 20 March 2017
The US Third Circuit Court of Appeals today upheld a lower court ruling of contempt against a chap who claimed he couldn't remember the password to decrypt his computer's hard drives.
The Magistrate Judge hearing the initial case, however, did not believe the defendant's claim. The judge "found that Doe remembered the passwords needed to decrypt the hard drives but chose not to reveal them because of the devices' contents."
That makes you wonder if the same rulings would be applied to politicians who tend to "forget" a lot too.
