"The aim of this investigation is to determine the impact of these surveillance activities on EU citizens", said leader of the Civil Liberties Committee inquiry Claude Moraes (S&D, UK).
"Surveillance has a huge impact on people. The NSA is not bound by EU laws and does not care about your laws, so it can wiretap anybody in your countries without any kind of warrant", pointed out investigative journalist and computer security researcher Jacob Appelbaum in his opening speech. "This is not a post 9/11 issue - the US has been doing this for a very long time", he added.
The use of UK anti-terror laws to detain David Miranda and UK government's direct threat that it would use the law to demand the destruction of material held by The Guardian are two issues for lawmakers to consider, said its Editor-in-Chief Alan Rusbridger via videoconference. He added that this could be "chilling and obstructive to journalism" and was like "throwing sand in the gears".
On the need for EU legal safeguards for media freedom, Mr Rusbridger stressed that "European journalists don't have the same protection as US journalists", underlining that Article 10 of the European Convention on Human Rights (right to freedom of expression) "doesn't have the same weight" as the US Constitution's First Amendment.
The importance of investigative journalism and the need to protect whistleblowers was emphasized by MEPs during the debate. "Lawmakers have a role to protect investigative journalism and to promote this kind of debate", said Mr Rusbridger. "Please find ways to protect journalism. It is only journalism that will give you an impartial view. (...) And please think about oversight mechanisms", he asked MEPs.
"For us the big issue is scrutiny", said Jacques Follorou, of Le Monde. "Debate in France so far has focused on the technological means used, rather than the law and citizens' freedoms (...) The point is that these technologies can be used for other purposes than to fight terrorism", he stressed.
"The key question in this inquiry will be why our systems of check and balances failed", said Sophia in't Veld (ALDE, NL). "We are in a scenario where there are no checks and balances at all", added Carlos Coelho (EPP, PT). "There should be controls to prevent this type of massive surveillance", agreed Cornelia Ernst (GUE/NGL, DE).
"This debate is important for lawmakers in all countries. It is an important role of Parliament to see how oversight is done", concluded Mr Rusbridger.
The Civil Liberties Committee has scheduled twelve meetings to take place before the end of the year. The next ones will be held on 12 and 24 September, in Strasbourg and Brussels, respectively. A resolution is to be put to a Civil Liberties Committee vote in December and a plenary one in January 2014.
