As a university student, I believe they are already mature enough to know what is the right or wrong thing to do. The current system of two strike you are out is like a game. If I am a NUS student and I know that the Uni will be lenient to me for my first offence, why not make used of the opportunity. NUS NTU should brief new Uni students about their zero-tolerance policy on this matter so that new comers will think twice about mis-behaving as there will be consequences.
