There are differences. The actors have sworn in court that they were not harmed, and were free to quit the video shoots at any time, which cannot be said of the inmates tortured in Guantanamo, Bagram, Abu Ghraib and elsewhere. The very fact that Paul Little was actually dragged before a court on the other end of the continent* is another difference, since torturers (thanks to Dungeonmaster John McCain) now have Get Out Of Jail Free cards no matter where they do their dirty work.On Friday in Tampa, Florida, Paul F. Little was sentenced by a federal judge to 3 years and 10 months in a federal prison after being convicted of the grave and terrible crime of distributing pornography "over the Internet and through the mail" -- films featuring only consenting adults and distributed only to those consenting adults who chose to purchase them. Even though he lived and worked in California, the Bush DOJ dragged him to Tampa, Florida in order to try him under Tampa's "community standards," on the theory that his website used servers physically based in Central Florida and some of the films were sent to Tampa customers who purchased them.
These porn prosecutions are the by-product of the demands from Senate Republicans such as Orrin Hatch, who simultaneously argue that (a) the Threat of Muslim Terrorism is so grave and "transcendent" that we must dismantle our entire Constitutional system and turn ourselves into a lawless surveillance state in order to combat it, and (b) the FBI and DOJ should use their resources to prosecute American citizens who produce consensual adult pornography. The same Alberto Gonazles who decreed the Geneva Convention to be a quaint relic in order to legalize torture announced in 2005 that adult pornography prosecutions would be his "top priority" as Attorney General (at his confirmation hearing, Michael Mukasey assured Hatch he shares the same concerns about "mainstream, adult pornography" as Gonzales did).
So as GG points out, you can actually rape and torture people against their will and the law won't touch you, but if you hire actors to pretend to do it, you get three-plus years in the federal pen. If this logic were applied to all performers, every movie producer, director and distributor who shoots scenes in which stuntmen and actors are injured or appear to be injured could face imprisonment. Depending on whether or not there's a statute of limitations, the producers of Gunsmoke (for example) could be dragged into court because Harrison Ford got his front teeth knocked out while filming an episode when he was a guest star 40-plus years ago.
* The Constitution forbids this kind of chickenshit:
In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defence.
