The Obama Administration has taken the unprecedented step of authorising the killing of a US citizen, the radical Muslim cleric Anwar al-Awlaki. The decision is extraordinary not only because Mr al-Awlaki is believed to be the first American whose killing has been approved by a US President, but also because the Obama Administration chose to make the move public. The Los Angeles Times reported in January that Mr al-Awlaki's name had been placed on a top-secret list of targeted killings. In the past 24 hours, however, a handful of intelligence and counter-terrorism officials have briefed Reuters and The New York Times on the decision. The authorisation ... and the decision to make it public is a high-risk strategy. Tina Foster, of the US-based International Justice Network, told The Times: "It is shocking that our Government would go to these extremes, even depriving someone of their life without a legal process." The policy of targeted killings is controversial. President Ford issued an order in 1976 banning political assassinations. Yet Congress approved the use of force against al-Qaeda after the September 11 attacks.
