I know this is from earlier this month but it was covered so briefly in the media and it is so enraging that I thought it deserved to be brought up again.

Luis Posada Carriles is a Cuban ex-patriot and admitted former CIA operative. He is also accused of being the mastermind behind a 1976 Cuban airline bombing that killed 73 passengers. Immediately after the bombing Posada Carriles was arrested in Venezuela and jailed in Panama for ten years until he escaped.
He has also been linked to a series of attacks on Cuban hotels,restaurants, and nightclubs as well as suspected to be involved in a plot to assassinate Fidel Castro during his visit to Panama.

Earlier this month Luis Posada Carriles was on trial in the United States charged with immigration violations. Throughout the trial the Venezuelan government demanded his extradition claiming Bush and the United States to be harboring a terrorist
saying that, "under the Convention for the Suppression of Unlawful Acts against the Safety of Civil Aviation (Montreal Convention) and the Convention for the Suppression of Terrorist Bombings (Terrorist Bombings Convention), the United States...is bound to investigate Venezuela’s allegations and to extradite or prosecute Posada Carriles if such allegations are well-founded."

Nonetheless, the judge threw out all immigration charges and Posada Carriles is now free.

For more detailed information on Posada Carriles, democracynow.org has an interesting article that was released before Posada Carriles was freed.
