There are so many other ways to expose the conditions of corruption to public. He can transfer his views/proofs to others who can publish them freely. He can make a group of loyal and sincere people to prevent the exercises of corrupt people. Even if he can not do any thing he was appointed on merit not in irregular way so no body can harm him and he can wait for the better time. But now nothing can happen so it is just like crying on split milk.
