If you're going to change the system, which you need to do to make it possible to bring charges in a case like this, the other changes I suggested would be more effective and harder to weaponize.
The core problem here is that the system allowed an innocent person to stay in jail. That needs to be fixed on a system level, not by trying to punish people after the fact for bad outcomes.
