A mother wailed over the death of her 10-year-old son in a freak accident on the school bus. "Bas! Chup (Enough! Shut up)," an officer screamed at her, wagging her finger. The disturbing video of insensitivity by a government official has emerged from a police station in Modinagar near Delhi, where the grieving parents of Class 4 student Anurag Bharadwaj sat on protest on Thursday, demanding action against the school for negligence.
