Want to understand why far-reaching, poorly scrutinized spying programs are dangerous? Here's why. The Intercept and the New Zealand Herald have obtained a document showing that New Zealand used the US National Security Agency's XKeyscore surveillance system to spy on other countries' candidates for the World Trade Organization's director general role. The 2013 snooping campaign searched for keywords in communications that referenced New Zealand's own candidate (Minister of Trade Tim Groser, above), the competition and the WTO itself. Any relevant results were passed on to a "trade team" within the country's surveillance agency, the Government Communications Security Bureau, which is rather alarming when the leadership run had nothing to do with national security.
