Thailand’s growing curbs on freedom of speech have seen a grandfather sentenced to twenty years in jail for insulting the country’s monarchy, while a U.S citizen awaits a possible similar fate in a ruling due tomorrow. Last month Ampon Tangnoppakul, 61, was sentenced to 20 years in prison on charges of insulting Queen Sirikit in four sms texts sent to an official working for Thailand’s former Prime Minister Abhisit Vejajjiva.
