Seems like the Associated Press just doesn’t like criticism. I’d assume the use of some of the AP’s images falls under Section 107 of Title 17 of the United States Code (AKA Fair Use), considering the usage was for the purpose of commentary.

Notwithstanding the provisions of sections § 106 and § 106A, the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified by that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright.

It also falls under criticism. Any lawyers willing to help him out?
