Links and bad neighborhoods.

I think it's highly unlikely that Google is going to penalize a site that occasionally links to a bad neighborhood.

If all, or most, or maybe even half of your links point to bad neighborhoods that's one thing. One or even a few such links mixed in among a bunch of good links is another, and far less threatening thing.
