To the Editors of The Crimson:

Contra leader Adolfo Calero is no stranger to the violent violation of free speech. In fact, he stands accused in an assassination attempt on Eden Pastora. On May 30, 1984 a bomb exploded at a public press conference in La Penca, Nicaragua called by dissident contra leader Eden Pastora (a.k.a. Commandante Zero). Eight people were killed including three international journalists. Many other reporters were mutilated.

Surviving ABC cameraman Tony Avirgan together with his wife Martha Honey investigated the bombing to identify the perpetrators. They concluded that Adolfo Calero and the C.I.A. ordered the bombing to assassinate Pastora. For at the press conference, Pastora was about to denounce the F.D.N., Calero's Somocista comrades, and his C.I.A. controllers, and publicly refuse to submit to their unified command.

Calero will face charges in Miami Federal Court next spring when he and 28 other alleged co-conspirators will go on trial for racketeering, drug-running, and terrorism. Contragate's "Secret Team" of Secord, Singlaub, Shackley, Rodriguez, Hakim, Owen and Clines et al. are joined with Calero as defendants charged under RICO, the Racketeering Influenced Corrupt Organizations Act.

The silencing of Calero at Harvard Law School did deny us an opportunity to hear this U.S.-sponsored terrorist excuse his violence. Hopefully, Tony Avirgan and his lawyer Daniel Sheehan, a graduate of Harvard College and Harvard Law School associated with the Christic Institue, will yet enable Calero to speak, but under oath and cross-examination.
