But still a huge population in india belives in this miscarriage of justice. Still in india Dalit people are not allowed to have relation with the normal people of general categories. Even their shodow is not acceptable. They can not walk on the common roads of a village because the are Dalit. They are forced to use the trackways so that other common people will remain safe from their touch and shadow.
