Sodium pentothal is no truth serum, its only in Holywood movies that they show that when administered person will start telling the truth. It sedates you so you speak without inhibition, so you may speak your thoughts out. Like for example krishna might be just be speaking whatever he has heard so far from media and police. If its a truth serum and if he is involved he should tell the full details isn't it, murder weappon persons involved and everything not 3 people may be involved....so on and so forth. Everybody saying its scientific tests....its very unscientific so no courts in the world accept it and I don't know of any other investigative agency using it.
