Last month technicians from GCHQ, the UK electronic surveillance agency, stood over journalists from The Guardian newspaper to make sure that they destroyed a computer containing files leaked to them by Edward Snowden, the former contractor to the US National Security Agency. This week the British police abused anti-terror legislation to detain David Miranda, the partner of Glenn Greenwald, a Guardian journalist, and seize his files. Coming up next: officials from the NSA and GCHQ bang their heads against a brick wall in frustration at having allowed Mr Snowden to abscond with their secrets. It would be as effective, and legal.
