One of the victim revealed that these Islamic Terrorists selectively chose NOT to kill Muslims and selectively mass murdered the Non-Muslims especially Hindus. This was also validated by other victims testimony and Mohamed Kasab's confession. Terrorists called their Muslim hostages as "brothers" and let them go unharmed.
So what exactly was Congress led UPA's Indian Government doing at the time?
Well, during that time, Muslim Rightist nonsecular Congress's heir Raul Vinci aka Rahul Gandhi was out partying till 5 AM in the morning and the whole Nehru-Gandhi-Maino family was seen celebrating at friend's wedding in the next few days. This is the same Islamic Terrorist attack about which Muslim Rightist Congress led Maharashtra Government's then Home Minister & Deputy Chief Minister Raosaheb Ramchandra (R.R.) Patil said "ऐसा नहीं है। इतने बड़े शहर में छोटा हादसा हो जाता है। तो total failure नहीं है।/Aisa nahi hai। Itne bade shahar mein chhota hadsa ho jata hai। To total failure nahi hai। (It is not like that. In big cities like this, small incidents do happen. It's is not a total failure.)". Hence, implying it was no big deal.
