It has been an infuriating few days for anyone who values the freedom of the press, as authorities in the United Kingdom resorted to the tactics of tyrants and thugs to squelch reporting that they simply don't like. In acts clearly calibrated for optimal intimidation, they have detained the partner of a journalist, threatened to shut down a reporting operation that has prompted a critical public debate over government spying and forced the destruction of a major publication's hard drives. It's breathtaking in its audacity - and if it comes to light that the U.S. government took any part in organizing, encouraging or supporting these acts, it will warrant immediate congressional investigation. As it is, the accelerating assaults on investigative journalism [indicate the need for] stronger protections for journalists and their sources. Using laws designed to ferret out suspected terrorists to detain a person aiding acts of journalism is a cut-and-dried abuse of government power, an act of intimidation that may well be illegal - and certainly should be. It gives the lie to the naive but oft-repeated notion that if you've done no wrong, you have nothing to fear. Such attacks on investigative journalism here and abroad appear to be escalating. The Justice Department has been caught spying on reporters at the Associated Press, and named a Fox News reporter a co-conspirator" in a leak inquiry. Judges have threatened reporters at both the New York Times and Fox News with jail time for refusing to disclose their sources.
