Our police is nothing different than Indian police.
What you know about Indian Police ?
We have 25+ states, except UP and Bihar Police is doing fine job.
Gora Police is corrupt too, but they dont do halla-sheri (promote) injustice in Bazaars. Indian Punjab Police is cruel also, but 99.99% no washing your dirty linen in public!
I saw video, very disturbing.
Police is aayina (mirror) of our samaaj. Government bodies should have grievances and complaints cell.
I think before finding out the solutions we should find out the causes for the same.
1. It seems that the salaries paid to the Police people are less, keeping in view the today's cost of living.
2. Common People themselves are responsible for this. We tend to offer bribe to the police people to get rid of the legal hassles.
3. Another reason associated with the corruption is the job security associated with it.
4. One of the major reasons is that the police people are dummies in the hands of politicians. Politicians control the postings and promotions of police officers according to their likes and dislikes.
If you stand and watch on the road, you can find a normal constable is making 1000 Rupees a day minimum from the fruit, vegetable vendors, and hawkers.
I suggest to replace all the police force with a new police system and conduct new recruiting process. It will be easy to clean the corrupted police from the system.
