This is futiel excersise, Narco test, Brain Mapping Test, etc. Our law which is driven by vote bank can not permit to put person behind the BAR if he / she happens to be from minority back ground and having good political connections.
So it is wasting of time so discuss it and larger majority are to be live in INDIA with fate to die in such blast and similar incident.
If people of India want to live for longer time then they have to wake up and throw those politician and party not only out of POWER but also from politics by actively participating in political affairs.
