Asim sir,
Care to elaborate your statement or have you pulled that out of thin Air ? Being such a senior member, we new members look up to you to give better comments than Mr BS Zaid Hammid. I personally have been hearing this theories (might be true ..) , but so far there was no conclusive proof. Mariot bombings , french engineers bombings , Lanka cric attack happened , people jumped onto the bandwagon and said "Its India" , but so far nothing has been remotely connected with India.Hell even Bangladesh mutiny has been blamed on India on this forum courtesy Mr BS MBI ( i am truly sure his idol mr Hammid) but again no proof it ,people who start this accusation suddenly go dormant and then they have to eat their words.
I highly respect ISI and PA in terms of capability to believe that if government is trying to push something under the carpet , ISI or PA would leak findings in the press; unless of course they themselves are culprit or fear that their involvment would get exposed. Again i would like to say maybe India does have to capability to stage attacks but till no proof is provided i would take this accusations as all gas.
All being said Highly this is terrible tragedy, such people should be arrested and then executed.
May allah/god/bhagwan/everyone give them peace (enuf blood has been spilled in the name of religion)
