I remember once we five freinds were strolling at night. A rickshaw is dashed by a car. A man with holding his pants and a belt moved out of the car and started pulling a woman from the rickshaw.Hadnt we all intervened the incident, the people would have taken her away. They were four and we five. Later we thought what if the man would have removed a gun?I agree there is a risk. But if everyone keeps quiet things will worsen and the devils will keep on increasing their might.
