Russia's Putin says NSA surveillance needed to fight terrorism
President says Russia 'not controlling Snowden'

President Vladimir Putin said on Thursday that the National Security Agency surveillance is necessary to fight terrorism, but added that the government needs to “limit the appetite” of the agency with a clear set of ground rules.
Putin’s comment at a major news conference was surprising support for President Barack Obama’s administration, which has faced massive criticism over the sweeping electronic espionage programme.
Putin, a 16-year KGB veteran and the former chief of Russia’s main espionage agency, said that while the NSA programme “isn’t a cause for joy, it’s not a cause for repentance either” because it is needed to fight terrorism.
He argued that it’s necessary to monitor large numbers of people to expose terrorist contacts.
“On a political level, it’s necessary to limit the appetite of special services with certain rules,” he said.
Putin added that the efficiency of the effort – and its damage to privacy – is limited by the sheer inability to process such a huge amount of data.
