There is a huge difference between helping one person (decreasing the general suffering by a tiny but attainable amount) and making one person an example (hoping this changes the status quo somehow).
Ortiz literally did not do her job. She over-prosecuted a case, apparently for personal advancement and DoJ-vendetta seeking, that was worth no more than a misdemeanor at best.
Sure, it's a problem that "the system" allowed her to do so. But it's also a problem that she abused the system, destroyed a life, shows no remorse, and will likely continue to abuse the system if not removed from office.
However, an investigation is merited to determine if Ortiz and Heynmann were willfully negligant in applying their tactics. The same way we hold other individuals accountable for harm caused by bullying, she may merit the same. My gut tells me that an investigation and possible trial would exonerate her of any criminal wrongdoing (unless some other over-zealous prosecutor treated her as she treated Aaron), but would leave her open to a civil lawsuit, which she probably deserves
What's the evidence for that?
