Contact her professional network, and let them know you don't approve of her actions. No tar. No feathers. Just make your own opinion known in the circles that matter to her career.
Let me get this straight: you want to contact a group of judges and prosecutors and "let them know you don't approve of her actions."
What exactly do you hope to accomplish by this? Federal judges and prosecutors already get this every day from people who do this for a living. And you know what? It doesn't work.
Who cares if you don't approve of what they're doing? They don't measure themselves based on your approval. They measure themselves based on their record of convictions, however they are earned. They are not directly accountable to you.
If you want to change something, let your local Congressional representative know you disapprove of how this prosecutor conducted herself. Your Congressperson is accountable to you, and he/she is the one in the best position to make change happen in this context.
I don't know how much more clearly I can state this:
Most criminal defendants do not kill themselves. It was Aaron's choice to take his life, not hers. Her professional and personal contacts will never agree with you that she hounded someone to suicide. Telling them "she did wrong" when it is not clear that she did anything out of the ordinary in this case will have zero effect on getting her "shamed" and will have no effect on ending her career.
The internet does not determine whether these people get jobs. People in the legal industry and in the federal government determine that. And right now as a member of the legal industry, I can tell you that despite my extreme distaste for prosecutors, based on all publicly available facts about this case she did not do anything wrong. She did her job, pursuant to the laws as they are written. You don't like that? Change the laws.
Going after her without changing the laws will not work.
That's a pretty arrogant statement in light of the general opinion regarding this case. It's also arrogant to think that someone, somewhere, will not find some means to destroy her career when at least tens of thousands will try.
You simultaneously claim that attempts to make an example of her will fail, and that such attempts should not even be made. Pfft. Something something before a fall.
