Bombay under attack

It is all over now. From the time Indhu called me to inform me about the terrorist attack in Bombay on Thursday morning till now many things have happened - all captured live on TV; the brutal acts of the terrorists, the heroic acts of the NSG commandos and the not so heroic act of the police (don't blame them, they cannot face an AK-47 or AK-56 with a lathi!!). More than 200 are dead and more than 300 are wounded in this madness. Properties worth many crores have been damaged; safety and security in 5 star luxury hotels are now questioned. The NSG Commandos had taken three days to flush out and kill the terrorists, numbering about 15. All Commado actions had taken place in buildings, not in the open. I have a simple question. Could the commandos have used a chemical stunner (like for example chrloroform or a similar chemical, like the one that comes in the not so intelligent advertisement that uses laughing gas to make the thieves laugh and forget their mission) to make all the people in the building unconscious and to act quickly to identify and catch the terrorists among the occupants of the building ? This could have been done in a fraction of the time taken for the conventional firing and bombing operations. We could have got the terrorists live which would have helped to provide solid evidence on the mission. What is your opinion? Is such a chemical available ? Has anyone used such a technique earlier to rescue the innocent hostages ? Should we ask this question to specialists ? Think.
