When the state acts without proper democratic authority, it acts as a rogue operation—as just another band of thugs with money and guns and a dangerous sense of self-righteousness. Whether the NSA's monitoring programmes are actually legal and effective may be more pressing questions than whether Mr Snowden deserves our esteem. But it became possible to address those questions openly only because Mr Snowden chose to speak up. If we wish to keep similarly pressing policy questions available for public examination, we must defend the honour of whistleblowers like Edward Snowden.
