The police is fully controlled by the hooligans of the TMC. Police can not take punitive actions for any violations by the ruling party cadres and their hooligans. If any one threatens you, and you counter him with a police complaint, and yet he is defiant, you can be sure he is part of the TMC nexus. It is total anarchy by the TMC, their cadres and their hooligans.
No improvement can be expected until the police works impartially, professionally, and with a sole purpose of providing service to the society. They need to unshackle themselves from the clutches of the ruling party, their cadres, and their hooligans.
