Whatever said & done, the whole tale is not as straightforward as Mr Krishna is making it seem. The CBI know this but poor guys, are shooting bullets in a dark room just hoping one of them will shoot down the prey.
This narco analysis business is an old practice and although it has some significance it is not fool proof and devoid of manipulation to some degree.
Krishna does seem to be involved in the whole affair or in the narco analysis test it would be next to impossible for him to fabricate the whole truth. However, the inconsistencies in his story makes you wonder that he is strongly avoiding vital truth.
One thing that keeps pointing its finger time and again towards the Talwars is their abject disregard to come out and explain themselves in all honesty and completion of the events. May be they have done this to the CBI, we don't know. But their sequence of events, their discovery of Aarushi and the after events of the murder make syou think if they were not a part of the whole thing.
My involvement with Psychiatry tells me that Mrs Nupur Talwar is well aware of the ehole truth in its entirety, at least thats what her body language says. She is hiding the whole thing for vested intersts ie saving Mr Talwar which is the obvious suspicion or is there a more bigger fish that she is hiding ie a serious medical or personal misadventure of Mr Talwar.
Krishna from his background appears to be a very "wafadar" ser
