After serving several Govts as IAS officer Mr Singh is trained to obey politicians and suddenly criticising politicians will not be appreciated.He played very safe,when he was young he obeyed Lalu because he had a career before him and after retiring from IAS now he has joined politics and is trying to be in limelight.One has to join a profession when he is young,all IAS officers who joined politics are having a common quality i.e., choose the right side and play safe and enjoy life.
