"In India, if any officer asks us to wear a safety suit and oxygen mask and then enter a manhole or sewer line, he is either ignorant or just mouthing platitudes, because there is no space to move inside. All we can descend in are our chaddis (underpants). They just want to fool us. They do not care because it is our bodies that are in the shit, and they believe our caste was meant to do this work."
