From the BBC:
A Cuban-born university professor and his wife who pleaded guilty to spying for Cuba have been jailed in the US.
Carlos Alvarez, 61, and his 56-year-old wife, Elsa, received a five and three-year term respectively for exchanging coded messages with Cuba.
Both said they took responsibility for their actions but had wanted to establish an open dialogue with Cuba.
But a Miami district judge said that their behaviour had undermined US foreign policy towards the country.
“As we know, a good motive is never an excuse for criminal conduct,” Miami Judge Michael Moore said before he sentenced the couple.
The pair were accused of sending coded messages about fellow Cuban-American exiles living in Miami back to Cuba.
Carlos Alvarez was accused of being in contact with Cuban intelligence agencies since 1977.
They claim that there was no secret information shared with Cuba, but as the U.S. attorney points out they went through great lengths to hide their identity and used codded messages. That really doe not sound like idle chit-chat to me.
