as per the decorum MR SINGH is holding such an important post . he is the security chief. if he is behaving like a indiscipline way is not bearable. although he will retire or wants compulsory retirement,it is true that indiscipline person  should not appoint on such post where the security will effect him. he is a man of egoistic. basically he is a govt servant. he served more than 35 years and and at present he is serving the highest post but he has shown his acts doubted. he has written the P M for the safety of the nation but the way he adopted is not genuine. i know he is facing inferiority complex. after the retirement he will not be respected by any one.
