Glenn Greenwald has made explicit that if the U.K. authorities intended to silence his or his colleagues' journalistic efforts by detaining his partner for nine hours at Heathrow airport, such intimidation tactics would not work.
Greenwald, speaking to reporters on meeting David Miranda, his long-term partner, at the airport in Rio, vowed to double his efforts in publishing information on covert, often unlawful government programs. Revelations about British spy agency GCHQ's secret involvement with and use of the NSA's dragnet surveillance programs have already served to embarrass the British government. Via Reuters:
"I will be far more aggressive in my reporting from now. I am going to publish many more documents. I am going to publish things on England too. I have many documents on England's spy system. I think they will be sorry for what they did," Greenwald, speaking in Portuguese, told reporters at Rio's airport where he met Miranda upon his return to Brazil.
