I grew up in small towns in Odisha and Jharkhand. Police using sexual violence on young tribal girls was exceedingly common there. My classmates who lived in tribal colonies were scared to interact with the police back in 1st grade.
These were 6-7 year old kids.

The pattern did not change in any city I went to. They routinely find people least likely to approach authorities and violate them. We say ACAB because cops use their understanding of the legal system and their power to exploit those at the bottom of the ladder.

If you pull up the data you'll find how shockingly common it is for women in Jails across the world to be consistently violated.
A major spot for this sort of sexual violence in India seems to be correctional institutions for victims of human trafficking.

It is also extremely common for these women to be solicited while they are still in the correctional facility. If not this then they are sent right back into sex rackets as soon as they are released.
Very few women actually end up escaping this cycle in India.

Here's a horrifying incident from three years ago:
TW- mention of sexual violence
In the Byculla prison 200+ inmates rioted because of the custodial death of a woman. She was badly brutalised and raped. The post mortem report showed a lot of details strikingly similar to Nirbhaya

That woman was beaten to death because she complained that her fellow inmates were not receiving enough food.
Do you know what happened? No cop was charged. 291 prisoners were booked for rioting.

Indian media focused on Indrani Mukherjee who was incidentally also in that Jail. They theorised about how she might have incited the riots.
Not a word about the victim was uttered on national media.
A woman died protesting for a basic human right and nobody even addressed it.

This woman lay on the barracks bleeding for hours before someone took her to the hospital. They only took her to the hospital because inmates were rioting in protests of her death.
Do not ever tell me that violent protests against police brutality aren't important.
