Post Modern Prosecutions (WARNING - it's Lew Rockwell.com, but it's the clearest explanation of post modern law that I have found)
Can't comment on the cases discussed in the article as I haven't been following them, but postmodern theory certainly pervades today's legal climate and underlies judicial activism, political correctness, and similar trends. Its influence runs so deep that even people not directly familiar with its theoretical formulation are influenced by it, so it's likely it influences the prosecution.
