Last week, the U.K.’s Parliament approved the Investigatory Powers Bill, dubbed the “Snoopers’ Charter” by critics. The law, which is expected to come into force before the end of the year, was introduced in November 2015 after the fallout from revelations by National Security Agency whistleblower Edward Snowden about extensive British mass surveillance. The Investigatory Powers Bill essentially retroactively legalizes the electronic spying programs exposed in the Snowden documents — and also expands some of the government’s surveillance powers.
