Hong Kong thugs demand people hand over their passwords

Hong Kong has given thugs the power to demand people hand over their passwords. The UK has a similar repressive law, which it used on David Miranda when he carried a copy of the Snowden leaks to Glenn Greenwald. It was a terrible mistake for him to carry with him the password to decrypt that data, and likewise a terrible mistake to pass through the UK on his way to Brazil. Someone involved with the Snowden leaks should have told him to avoid those risky choices.
