National security law/ Dutch government is studying its new intelligence laws

American whistleblower Edward Snowden has reaffirmed his doubts about the effectiveness of massive wiretapping, citing the recent attacks in Paris as an example.

"France passed one of the most intrusive, expensive surveillance laws in all of Europe last year and it did not stop the attack," Snowden said in an interview broadcast by Dutch TV channel NOS on Wednesday. "This is consistent with what we have seen in every country."

The mass surveillance has not stopped a single attack in the United States, he said. "It didn't stop the attacks in London, didn't stop the attacks in Spain, didn't stop the attacks in Boston."

Snowden came to international attention in June 2013 after disclosing thousands of classified documents he acquired while working as a contractor for the U.S. National Security Agency (NSA). He is charged in the United States with espionage and was granted asylum by Russia in August 2013.

Currently, the Dutch government is studying its new intelligence laws and the call for an even broader tapping capacity covering even all internet cable traffic such as emails.
