I believe the problems like this stems from the first moment that jurisprudence accepted their first plea of "not guilty by reason of ..." Most of us are of an age and from a civic background that when we were young you understood that you were either guilty or innocent, with no shades of grey in between -a nd you guided yourself accordingly.
The moment we started entertaining "soft verdicts" is the minute we started down this slippery slope of tolerating excuses for immoral and/or criminal behavior. Add celebrity status and political slant to the mix and you have the mess we have today. That's not to say that the rich and powerful didn't always find ways thru the cracks, but generally after they were disgraced once they stayed that way.
Not any more.
