In the Saturday Washington Post Metro section, "Limits to Religious Liberty?" would be of interest, especially the commentary regarding cartoons of Mohammad and South Park, but I can't find it online. The link to the print edition of the paper sends you to the Saturday On Faith blog.
At the blog I was able to find a few relevant articles, although not most of the ones quoted in the physical paper.
