Even though they are only about 13% of the population of India, Muslims account for the majority of the savage violence in that country.
This happened in Jammu/Kashmir, which is only nominally an Indian state. There’s a huge overflow from Pakistan, the population is majority Muslim, and the actual government in Delhi has only tenuous authority there. The state government is highly independent and often resists Delhi’s authority. Also, this is the police stepping way outside their jurisdiction, even for J&K, and though you won’t hear about it in the west, with the Indian government on an anti-corruption crusade right now it’s a fair bet that there will be a significant purge of the offending officers. There’s a big to-do about whether or not to lift the Indian Army’s emergency authority in the region, so this kind of thing isn’t going to help.
India has the 2nd or 3rd highest population of Muslims. There are enclaves of huge majority Muslims. I have to believe the police chief has to be a Muslim.
