Hi everyone. I was just thinking that it would be nice to see Batman take on some criminals whose crimes are a little more taboo. There are so many silent epidemics in this world and I think that it would be cool to see Batman take on a villain who dabbles in something along the lines of child abuse, sexual crimes, etc.. Does anyone know of any instances (from graphic novels perhaps) where Batman has encountered any of these crimes? Better yet, have any of the members of Batman's Rogues Gallery ever been known to commit such crimes?
