Rusticate a few scumbags, transfer a few teachers, sue a few 'students', send notes of warning to parents and these 'revolutionaries' would start whining like weaklings they are. So far they have been encouraged by central governments, they don't know what it is to be hit by full force of government machinery. This is as good a chance as any for action. The general public don't care and is not interested in this JNU circus, the english news channels would whine for a while and then move on.
