The editor of the UK’s Guardian Newspaper says he plans to published more revelations about US and UK spying from the trove of intelligence secrets smuggled out of America by fugitive leaker Edward Snowden – and this is despite warning from the new head of Britain’s MI5.

Andrew Parker this week gave his first speech since being named Director General of the UK’s domestic security service in April.  He didn’t refer directly to Snowden, but said that terrorists now have greater understanding of how the UK and US are able to intercept the way they communicate nefarious plots.

Guardian reporter Glenn Greenwald wrote a series of blockbuster stories based on Snowden’s information detailing the size and reach of the US National Security Agency (NSA) and Britain’s counterpart Government Communications Headquarters (GCHQ).

Guardian editor-in-chief Alan Rusbridger replied that Greenwald “has a phrase that you would have to be a terrorist who didn't know how to tie his shoelace not to believe that people were watching things on the Internet and scooping up telephone calls.  I don't think some of this will come as a great surprise to terrorists.”

Meanwhile, Edward Snowden lives under political asylum in Russia, but Brazil-based Greenwald has another plan:  Greenwald is asking Brasilia to grant asylum to Snowden.  The Brazilian government is plenty angry at news that the US and Canadian governments routinely spied on the communications of President Dilma Rousseff, several key lawmakers and trade agencies, and the Petrobras energy company.
