Violation of Norms

Yesterday when I was travelling in MTC bus from Velachery to Medavakkam, few college students [not really sure which college they belong to] got into bus @ Vijayanagar junction. They were standing on the steps [as most youngsters do] and start hitting the inner roof along with a song. It was really irritating for the passengers but no one turned out to tell them to stop. I being one among feeling guilty [Eventhough I feel some authoritative power should be there, I also has to accept the fact that its every citizen's responsibility to fight to get their rights]. Bus Driver told them to stop twice but none of the college guys listened. He stopped the bus at Madipakkam signal and went for calling Traffic inspector. As always, before the Traffic police came students went on to catch the next bus. And they again got into the bus when the bus neared Narayanapuram stop. This time again they started doing the same and were challenging driver that no traffic police will come for the rescue. I wonder who had given right to them to enjoy at the cost other's precious time. Who had given such over courage not follow norms when one should follow it in public. Main victims are Bus drivers and passengers. I would suggest bus drivers should be given a toll free number of the traffic police with which they can contact and take immediate action.
