When Fernando Gonzalez walks out of an Arizona prison next week, the “Cuban Five” will be down to three.

Intelligence agents in the employ of Fidel Castro’s Cuba, they were arrested in the United States in 1998 and given terms ranging from 15 years to consecutive life sentences on charges including conspiracy and failure to register as foreign agents. A federal appeals court upheld their convictions but voided three of their sentences, including Gonzalez’s, after finding they had gathered no “top secret” information.
