The existence of the Manual Scavenging even in this age just shows how much our society is casteist to the core and how much the caste discrimination is institutionalized and normalized in all the institutions and society.
And the law which was passed to protect the oppressed poor people, had been used to harass and bully them. From "Unseen, The Truth about India's Manual Scavengers, by @Bhashak
22-year-old Ranjithkumar stands forlorn outside a government mortuary in Royapettah, Chennai. Dressed in a black T-shirt, he runs his fingernails darkened by grime across his face, a vacant expression in his eyes. His hair is matted with muck, specks of which cover his clothing. But when a friend hands over a wet cloth to help him wipe off the dirt, he waves it off, choosing to keep the reminder of a traumatic night - one which he survived, but his brother Arunkumar did not.
