hindu agitation in JK started with this cave, so this is the cause. it is not a side-effect. mere side-effects do not cause a month of riots and strikes.
the fact that KP's live in slums in jammu is a matter of shame for indians. india never even helps these people build even a decent home. these people were loaded onto army trucks, brought to jammu, and then given a tent and some bottles of water. they were kicked out of kashmir by muslims, but they continue to live like ants because india doesn't really care about them. they are a small community after all, and 300,000 people isnt a significant voting block in india.
