Now to the case of Cuban-born militant Luis Posada Carriles. The Miami Herald is reporting that Posada used a false Salvadoran passport to fly into the US in the spring of 2000 — about six months before using the same passport to travel to Panama, where he was arrested in connection with an alleged plot to kill Cuban leader Fidel Castro. The paper cites documents from the Department of Homeland Security. Use of a false passport to enter the country is a deportable offense in its own right. Posada was taken into U.S. custody on May 17 after sneaking into the country this year. But the records filed in his deportation case in El Paso, Texas, raise questions about just how often the former CIA operative has visited the US. A travel record included as federal evidence against Posada shows he arrived at Miami International Airport on a flight from Central America on April 26, 2000 carrying a Salvadoran passport in the name of Franco Rodriguez Mena. So far, Posada has been charged with being in the country illegally. But use of false documents is a federal offense that could result in a sentence of up to 25 years in prison if the false document was used for terrorism purposes. U.S. government officials declined comment. The immigration charges against Posada pale in comparison to the long list of allegations against him. Among them, masterminding the 1976 bombing of a Cuban jetliner that killed 73 people.
