Nicolas, thanks for link to startpage, I'll look into that.
Xenia's right, blind faith in 'the authorities' is a. clearly misplaced and b. ignores the fact that 'the authorities' are people, some of them nosy/malicious/tempted to commit fraud.
scaevola and itsallgoing to be are also right that this is a huge deal - the security services in the US and UK have been revealed as flouting the law on a massive scale.
People who shrug their shoulders - do you not care about democracy? Are you happy to live in a police state?
Surveillance of suspected terrorists is permissible and desirable and is subject to proper judicial oversight in the UK. Only it turns out the spooks have been merrily ignoring that and spying on everyone, illegally and without discriminating between suspect and innocent person.
If the state deliberately, knowingly and secretly flouts the law, how does that make the state 'better' than the sort of criminals they claim they are after?
