You need to understand that US Attorney is a stepping-stone job, especially if she is very vocal in her role. Ego-maniacs like Rudy Giuliani use it to bypass the normal political machinery to get a mayorship, congressional post or cabinet/justice appointment. Others use it as a path to the ultimate job -- lifetime prestige and employment as a Federal judge.
"Naming and shaming" gives her name recognition and boosts her credentials as "tough". Any publicity is good publicity for a politician.
Instead, you and your friends should be asking the Senators and Governor of Massachusetts (aka the gatekeepers to this person's career path) why someone who demonstrates such contempt for the concept of justice is representing the United States government. You should ask President Obama and the Attorney General why their administration tolerates that contempt.
If you want the law changed, you need to attack those who are perpetrating injustice.
Even if there are other overzealous prosecutors in general, getting rid of this one would be an important message. So this is an important step, even in the absence of practically impossible outcomes like decriminalizing copyright infringement.
Overzealous prosecutors hurt people accused of every kind of crime, making them accountable is a pretty far reaching cause.
However, it is a story that could serve a larger purpose than just ruining this woman's career. I would like to this effort put into something more constructive like the decriminalization of copyright infringement. It could be relegated to a civil issue, especially online (versus manufactured goods).
There will be other overzealous prosecutors to replace her, but if the law is changed. It could serve a greater purpose.
