I heard that the sikh community has been created to destroy the muslims in india. that is created based on hatredness against muslims. It is an oath that they will not cut their hair until the last muslim is chased out of india. However, it is very bad on part of ahmed who a sikh student's hair. He should be punished and the punishment should be a lesson to others.
But the loop holes in legal system make the criminals to escape.
