I understand the anger and emotion that people have over such horrendous crimes. We all do. To not get that is to define oneself as something rather disturbing.
But, there's something bigger here than just JS, imo. There are many horrendous crimes committed all over, and we owe it to victims and the sometimes wrongly convicted (not talking about JS here) to insist on fair trials, even for those we assume to be guilty before the trials start. The relative ease with which the first and loudest narrative can be permanently imprinted in the minds of the general public isn't unique to just this case. Sometimes it's the truth, sometimes it isn't. That's why I think we need truly fair trials regardless.
Along with that concern, I maintain that if the State can figure out a way to put Curley, Schultz, and Spanier in jail, for basically nothing more than the PR/political gains and to cover the missteps from years ago, then they can figure out a way to put (proverbially) you and me in jail for no real reason.
The whole of the issue goes more to judicial fairness and accountability than to only JS and that specific case. The OGBOT got away with something sinister, the local attorney got away with something unethical, the State of PA got away with a stunt that severely impacted the lives of very good people.
