While I am completely against the prosecution in this case, I think the reality is that there's no way you are going to make the prosecutors legally accountable. Maybe in civil court. I think the difference legally between bullying, as you describe, and what the prosecutors did, is that the prosecutors could argue they were doing a job they swore an oath to perform. Nevertheless, I don't know what the possibilities are but I hope there are civil ramifications for the prosecution and hopefully reforms and positions to be filled.
