So what happened was, these 'people' were celebrating what happened to our brothers and sisters in 1984 (in a bad way, as in they loved the success of darbar sahib). The police blocked the other singhs from coming, but one singh behind shouts the jaikara while chasing them and they all start running.
Akaaaaaaaal!
