NEW DELHI - Around 20 people have been arrested in India, accused of failing to stand for the national anthem in cinemas, police said Tuesday, two weeks after the country's top court made it compulsory. The Supreme Court ruled on November 30 that cinemas should play the national anthem before every screening, and that the audience should stand, drawing angry accusations of an assault on civil liberties. "All the cinema halls in India shall play the national anthem before the feature film starts and all present in the hall are obliged to stand up to show respect to the national anthem," the judges said.
