I'm not trying to suggest that there's nothing that can be done, though I can see how you might interpret it that way, or that it's harder now than in the past, though I can't possibly see where you got that from. I'm simply saying that the "justice" system cannot be fixed without completely dismantling and replacing it, and that's not something you're going to do by changing a few laws or even releasing thousands of prisoners. Both are good ideas, but neither change the inherent injustices in our system of which there are way too many to even list. Plea bargains, mandatory minimums, criminalization of everyday activities, habeas corpus (or lack thereof), policing for money, prison officials that encourage rape and violence, racial profiling, different judicial outcomes based on wealth, police committing blatant murders without recourse or consequences, etc. are all huge problems in our current system and are not going to be fixed by a system that can't even ensure its basic principles (the constitution) is upheld.

I don't see it as "fatalist," at least not in a negative sense. It's quite possible that the average person does have effectively no control over policy, and that one's time is better spent directly making one's life as best as possible by fostering relationships, furthering one's career, enjoying hobbies and entertainment, etc.

And of course I don't think it's now harder than ever. I'm not sure where that notion came from.
