So the system is fucked, as I see it.

It feels broken because it is broken. But if you weaken procedural safeguards to ‘fix’ it, you don’t get justice - you get lynch mobs. Sometimes quite literally. There have been people beaten to death by neighbors because they were declared a sexual offender online - which later turned out to be wrong.

A criminal justice system has to protect even the accused against injustice. If it doesn't, it's not justice, but just a kangaroo court.
