1.) I desire truth to be revealed, but I understand that sometimes in order to protect the populace, it mustn't be revealed.
(In this case, hiding the truth is good)
2.) I also realize that the powers that be will sometimes hide truth, not to protect the populace, but to protect themselves and allow their deceit and unscrupulous behavior to continue.
(In this case, revealing the truth is good)
Now, discerning the difference between 1 and 2 is not at all easy as one might think since, what we are talking about are hidden, and only revealed in parts and pieces.
