One of former CIA agent Edwin Wilson's trials started Monday.
Mr. Wilson is charged with illegally supplying a Libyan intelligence officer in Europe with four revolvers and an automatic rifle. One of those weapons is said to have been used in the slaying of a Libyan dissident in Bonn. Charges in the other pending trials, two in Washington and one in Houston, include conspiracy to commit murder, illegal export of high explosives, and recruitment of former Green Berets to train Libyan ''hit men.'' One of Mr. Wilson's lawyers warned: ''If the government makes us go to trial, my client will be forced to reveal information that will shake the CIA to its foundations.''
