And seriously, no one writes about the cleanup the rest of the police force must have to do when McClane storms through an area.

That's because the idea is too appalling. :) when I was cleaning out my comics, I found old issues of a Marvel series called Damage Control, about the team of poor schmucks who go out and clean up after superhero battles. I think action heroes probably need their own specialized team -- the special forces/commando version of the guys who clean up the blood at crime scenes.
