Only one thing can be learnt from Aarushi murder case probe..is to keep media away from murder investigation. 1) As it is clear now that ,It was krishna who misguided police about hemraj and aarushi in objectionable...etc. 2) It was krishna who cleared all the evidence from the scene of crime by cleaning everything..telling others that it was police who instructed him 3) media's undue pressure instigated police to come out with ...wrong investigation. 4) Media people in a greed to know more on aarushi's illicit relations tried to hack her email id and password..mobile bills etc... 5) But Krishna is the smarty cultprit..i wonder and zapped by the way he tricked police and made this case so vulnerable that even now cbi do not have concrete evidence against them.
