Capitol, demanding a limit to the government's surveillance programmes.<br/> <br />Some of the demonstrators held banners in support of Edward Snowden, the former contractor who revealed the extent of the National Security Agency's spying activities.<br/> <br />The march attracted protesters across the political spectrum.<br/> <br />(SOUNDBITE)(English) MICHAEL GREENE, ANTI-SURVEILLANCE PROTESTER, SAYING:<br/> <br />"I'm outraged like most people here at the mass surveillance that's going on and people just don't seem to be upset about it. It's blatantly unconstitutional."<br/> <br />The demonstration was organized by a coalition known as "Stop Watching Us", that consists of around 100 public advocacy groups and individuals urging Congress to reform the way the NSA gathers intelligence.<br/> <br />But despite these protests, the Obama administration says gathering online data secretly is crucial in protecting the U.S. and thwarting militant plots.
