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.
