If you read the link I posted, it talks about the lack of prosecution of alleged culprits. Also, the abuse was systematic and widespread, so much so that, according to Wikileaks, US diplomats in India privately discussed it.
Once again, the army's role is to exert psychological pressure..
Let me explain.
When animals are "trained" in some parts, they are punished using electric prods which inflict intense pain. Once the animal is conditioned, the "trainer" only needs to use a wooden stick. The animal reacts the same way because it has been psychologically conditioned to fear the stick -- even though the.stick itself may never be used.
In this context, the IA was directly involved in brutalizing Kashmiri civilians in the past. The current set up may put the RR and local police as the front line, but the IA still remains close by. The AFSPA still authorizes the army get involved if need be. Whether the army will or will not is irrelevant. The Kashmiri civilians are not going to bet on what the private contingency plans of IA are either way.
The point is that, due to past behavior and current physical capability (due to proximity), the Kashmiri population has been conditioned to fear the army as a brutalizing force.
