I've been thinking, lately, of bat-comics about crimes that can't just be punched into submission the way Batman or Robin can slug a mugger and stop the mugging, slug a murderer, stop the murder. You can't punch out addiction. Vachss and Goodwin/Hampton showed Batman that you can't slug child abuse and end the crime.
And, of course, there are crimes that are crimes because the acts are illegal, but not worth punching or even, really, from Batman's perspective, cracking down on. Batman doesn't drop you for jaywalking, he's even overlooked the occasional pot dealer or squatter.
Batman pulled Ellie out of prostitution, across Morrison's Batman run, but he didn't harass her or any of the other women, and didn't even push anyone else to quit. Ellie really wasn't "up to it." She was a scared, depressed kid in an adult world (on top of which, the cops were ready to use her to pacify a rapey murdery ex-cop and nobody needs that in their life).
Any good recommendation for "he can't fix this" stories, where Batman still does all he can?
