"Police Officers alone, and none else, can give evidence as regards the circumstances in which a person in their custody comes to receive injuries while in their custody. Bound by ties of a kind of brotherhood, they often prefer to remain silent in such situations and when they choose to speak, they put their own gloss upon facts and pervert the truth. The result is that persons, on whom atrocities are perpetrated by the police in the sanctum sanctorum of the police station, are left without any evidence to prove who the offenders are."
