You mean 'increased', right?
I can't put reconcile those facts for you. Actually, I seriously doubt the accuracy of the 60% Muslim-40% Hindu numbers someone on (this?) thread quoted.
But I'll tell you what I do know, for fact.
Hindus used to be a significant minority in the Kashmir Valley. Today, they are (almost) all gone. Most of them have left their homes for Jammu and other North Indian locales like Delhi. Jammu was, and still is, predominantly Hindu. However, the Muslim population of Jammu has also skyrocketed due to economic migration of Muslims from the Valley, seeking work. Most terrorist activity occurs in the Valley, which is now almost all Muslim.
As for who's dying.. Indian security forces are comprised of the army and the paramilitary border security forces. The paramilitary forces are known for their lack of restraint. Plenty of innocent Kashmiris have died, most of them Muslim, because of this. Muslim terrorists, on the other hand, will spray bullets into a crowd to get an Indian soldier. Plenty of Muslims die this way, as well. More Muslims die than Hindus because there are just so many more of them, and because most of the "action" is in the Valley and other Muslim areas.
I'm guessing there isn't a big demand for lawyers over there. Disputes get settled with distinctly un-legalese dispatch.
And what was the probable motive? Trying to quit the family?
Kill all the relatives (extra points for kids) of any wavering soul. Makes it kind of hard to quit the Mosque.
