There must a thorough investigation by appropriate authority( Not CBI please), and their report should be made public, as to the sequence of events that led to nand lal's harassment by cops. This should help to serve as an eye opener for all future cases( and past) where thre is unnecessary harassment of the common man. the victims should be given the probable approches if such a thing happens to them and these procedures should be publicly exhivited. A thriving democracy like india should not be a police state.
