Exactly. The STATE has to presume that Sandusky is innocent until proven guilty, no matter how damning the evidence looks. The rest of us are under no obligation to ignore the obvious.
Actually THE STATE presumes him guilty and tries to show that in a court of law. The court presumes him innocent and THE STATE can not deprive him of his liberty or property unless THE STATE can prove beyond a reasonable doubt to triers of fact, jury or judge as the case may be, that he is guilty of something.
