It will take time.... Threat perceptions are changing..... From the days of Lathi, and 303, now Police is getting assault rifles, automatic weapons.... It wont happen over night.... There is progress, but is it adequate??? "NO".....
From what i know, The Police force capabilities can be divided in two .... Before 26/11 and After 26/11.... Mumbai attack gave a rude shock to entire police force of India.....There was panic and there were swift actions.... but over a period of time the progress has slow down.... May be another shock will awaken them again......
