Mask ke pichey kya hai: Who were the 'masked goons' at JNU?

First it was ABVP goons, then it was leftist terrorists, now it's a fringe Hindu group. Meanwhile, Delhi police probably didn't even think that there was any violence. Maybe that's why the street lights were switched off, suspicious civilians were allowed to enter JNU, and the police slipped into a stand-up slumber. But we are a tad bit confused all these investigations into the masked men and women. Will the real 'mobsters' please stand up?
