Imran Babar just unfolded an ongoing practice in police department. It is very common and usually DSP & SHO always abide by the instruction given by their high-ups. PSPs are also reponsible for corruption and minsmanagement in police deptt. There should be an to the all kind of corruption whether by Rankers or PSPs (Juniors are not always corrupt). If proper inquiry and accountability is done then mostly officers of police both PSP and Ranker would be exposed. Wait for the time!
