A U.S. man sentenced to 30 months in a Thai prison for insulting the king has been freed by a royal pardon. Joe Gordon was convicted in December for translating parts of a locally banned biography about King Bhumibol Adulyadej. U.S. Embassy spokesperson Walter Braunohler said he does not know the reason for Gordon's release, but said he was pleased with the news. He said they urge Thai authorities on a regular basis here in Bangkok and also in Washington to ensure that freedom of expression is protected in accordance with international obligations. Under Thailand's laws, anyone convicted of insulting the monarchy faces up to 15 years in prison.
