Above two are the cases in which they were exposed. When investigations are done with the aim to arrest muslims, then how can you ensure that the investigations are un-biased.
In samjhuta exp. blasts, your army's explosives were used, your on duly colonel was involved. That was busted by Karkare who was killed in 2008 attacks. These hindu terrorists in above case nothing but scapegoats to keep the 'big game' remained hidden.
It actually your army who doesnt want peaceful talks with Pakistan, whenever there is some improvement, incident continue to happen, when karkare was about to expose the entire Army network responsible for terrorism in india, he got killed in mumbai drama.
