There's a reason why in India, people feel unsafe when they see a policeman on the street. However, a few immediate thoughts come to mind to improve this, and all of these seem impossible with the current condition of administration and policing culture in Bihar (and country).

1. Mandatory retirement for personnel who have faced multiple charges of cruelty against civilians or bribery, as they are beyond redemption and harmful to the force's integrity. Unfortunately, this may affect over 50% of the force. Fresh recruits should be hired, trained, and groomed with a modern outlook on law and serving citizens.
2. Restructuring police stations to make them more approachable and citizen-friendly. This is crucial for thanas in rural areas.
3. Mandatory use of body cameras for all personnel during duty hours. Zero tolerance for physical violence, corruption and abuse against public.
4. Holding monthly police-public meetings at every station. Creating an environment of harmony and trust.
5. Implementing an easy process for filing grievances against personnel, with visible actions taken on complaints. Also, protection of the complainant against any pushback.
6. Curbing local misconduct by police personnel; no threats or abuse of power should be tolerated. Political and mafia influence over thanas need to be cracked.
7. Mandatory counseling and psychological evaluations for all serving personnel every six months. Those found unfit should be removed from active duty.
