>>is trying to take the territory back
Back? It's a part of India.
Let me enlighten you, these come over the border from Pakistan, are hopefully killed before they do too much damage.
Try reality.
What you refer to as a "border" is actually the "line of control" that divides that small country.
The population on both sides of that line is and has been predominantly Moslem for hundreds of years (albeit with a tradionally Hindu government up until Independence).
So, who would grab a Shia, torture him, and then slit his throat. Well, could be a bunch of Twelvers who don't like Seveners (if the guy was a Sevener but nobody said). Or, it could be a secular gang to which he might have refused to pay bakshish. Or, maybe it's some people who didn't like his dental work ~ torturing him shows pretty much that they knew that he was a dentist.
Or, maybe a bunch of Hindu extremists caught and killed him for any one of a variety of reasons which might include not wishing to pay their dental bills, or because he was a Sevener (and since almost all the Seveners are doctors, et al, in Pakistan, and India, that's not far fetched), or because he was in the wrong place at the wrong time and saw something he shouldn't ~ e.g. former customers from Saudi Arabia!
Ah, yes, AlQaida operatives in Kashmir saw someone they didn't trust who could identify them so they tortured and killed him in front of a crowd of onlookers.
Sure sounds like that must be the solution eh?!
