I see. Freedom of Speech - not so much. I anyway had my encounters with immigration in Singapore once. They asked me "Are you leaving the country through this airport as well?" and I replied "Well, we thought about visiting Malaysia as well" whereafter she raised her hand and the police brought me into this weird room where I could not use phones/computers etc. What a treatment for a European citizen. I had plenty of money and proper travel plans. They also released me after 30 minutes, but I felt really bad after his experience, basically treated like a criminal. Now I learned just to stfu while talking to officials at airports.
