Moscow - The National Security Agency's mass surveillance of telephone and Internet data has eroded constitutional protections and is "setting fire to the future of the Internet," Edward Snowden said.The whisle-blower of the documents revealing the NSA's top secret surveillance programme appeared via live video chat Monday from Moscow to address the South by Southwest Interactive Festival in Austin, Texas.
Snowden said that the NSA surveillance was so massive and unfocused, the world became less safe because the government was less able to focus on suspected terrorists, such as the Boston Marathon bombers whom the United States had been warned about by Russian intelligence.
