Given that the state always has more resources available than individuals it prosecutes, cases like Aaron's are powerful arguments for a limited government. A real limited government, not the kind that just keeps hands off hackers and turns their arsenal of weapons on another class we care about less. I realize this perspective is completely out of vogue these days, but the fact that governments oppress individuals is an age-old truth that needs to be relearned over and over, it seems.
Asking prosecutors to be "nicer" won't cut it. Nor will firing one and replacing them with another, tasked to enforce the same law. We must remove some of their power, meaning many laws need drastic change or repeal. It's sad that it takes a high profile individual to raise concern when plenty of others have been destroyed before and gone unnoticed.
