At the second SMU Ministerial Forum held on Wednesday, Law and Foreign Affairs Minister K Shanmugam said that dealing with Singapore’s long-term demographic needs is the biggest challenge facing the country in the next 20 to 30 years. On questions about whether Singaporeans would be jailed for organizing protests at Hong Lim Park, Minister Shanmugam stressed that while certain topics are off limits, "there are no laws prohibiting you from protesting. If you want to go out and carry a placard and do a mass protest, go to Hong Lim Park. But if you want to say something on politics, express yourself at forums and blogs and write to the media.”
