When you fear criticism, then what is being said must be true. You are one of the most useless institutions out there and that is because you are populated with incompetent, corrupt and self serving individuals whose usefulness has expired and whose goals and objectives benefit no one but themselves.
As a citizen, I have the God given right to say all this and as a human being, I can do that also. If you are not going to do anything good with yourselves, at least don't do anything worse. Let the man go, if he has not said anything true, why are you worried? And if he did do something unconstitutional, there are the appropriate channels to bring him to justice.
Or are you planning to come for the rest of us too?
