Yeah the glorification of the police and privileged feels a little bit tone-deaf if you're not given to glorifying the police and the privileged (which, unfortunately, Batman writers seem to tend to be).
Right; Bane's POV is completely unsympathetic in the context of DKR itself. The preceding two movies are absolutely essential to remember that, oh hey, yeah this WAS a corrupt-as-fuck police force, and all these people in prison got there because of a law hurriedly passed based on a lie. (The latter, at least, gets some emphasis, but it's really easy to forget how corrupt the Gotham cops were in the first two flicks given how squeaky-clean they are in this one.)
If you manage to keep that stuff in mind, it's a little easier to see the villains' point and think that maybe if they'd, you know, tried to settle it with lawyers instead of nuclear weapons they'd have been sympathetic.
There's another point that's in the novelization that's been
making the rounds:
Blackgate Prison was a maximum-security penitentiary located on one of the smaller islands in Gotham Harbor. Now that the Dent Act had made it all but impossible for the city's criminals to cop an insanity plea, it had replaced Arkham Asylum as the preferred location for imprisoning both convicted and suspected felons. The worst of the worst were sent here, except for the Joker, who, rumor had it, was locked away as Arkham's sole remaining inmate.
Or perhaps he had escaped. Nobody was really sure.
Not even Selina.
So if I'm to slap some boldface on a couple of bits:
the Dent Act had made it all but impossible for the city's criminals to cop an insanity plea
the preferred location for imprisoning both convicted and suspected felons
So yeah we're actually looking at some pretty shady stuff going on here -- I just mentioned that Batman is a story about a rich man beating up the mentally ill (a point REALLY hammered home in Arkham Asylum the game; the bits where gibbering madmen run at Batman and he just fucking brutalizes them are really pretty chilling). Well, here we have a city which, at least if we're to take what we know about the Batman mythos for granted, is populated by a BUNCH of violent crazies, and...now, based on a lie, none of them can actually get remanded to psychiatric care, and indeed they don't even wait for a TRIAL to throw suspects into goddamn Alcatraz.
And oh yeah -- it's CO-ED!
(In fairness, it's not like Arkham was ever a state-of-the-art mental healthcare facility.)
(Also in fairness, this is a pretty good representation of Bane's creators' viewpoint; they actually did an arc where a namby-pamby liberal tried to explain that all Batman's rogues were just unfortunate victims of mental illness. As you might imagine, he was not the hero of the story.)
(Also also in fairness, Dark Knight Returns did that years before. And is one of the most politically-schizophrenic superhero stories ever. Hard to dismiss it as a right-wing fantasy when it spends so much time depicting Reagan as a fascist.)
But... he didn't grow up in a pit. He's just a big kindhearted guy who ended up there and... got facestabbed trying to keep a child from getting raped and became a nihilistic terrorist, I guess.
I assumed he was born there, same as in the comics, but I guess that's a point I'm taking for granted.
