I think he may even be suing me

William Rodriguez has filed the sort of lawsuit that you normally expect to see from a pro se litigant, the sort that under normal circumstance even a lawyer wouldn't want to associate his name with. But Mr. Rodriguez managed to find representation for his RICO complaint against, well, pretty much everybody for planning, conspiring, covering up and lying about about the 9/11 attacks. The list of plaintiffs even includes such noteables as Kevin Smith, who as far as I know is a movie director and comic book writer.

32. Against the criminals who have hijacked not just four airplanes but the government of the United States, and who have virtually unlimited financial and other resources at their disposal, stands a solitary American hero — whose valor shone brightly on that day, as defendants were flown hither and yon, and skulked in “undisclosed secure locations.” Plaintiff has continued to shine in his selfless, unpaid efforts to relieve the suffering of the victims, as the defendants have launched wars and inflicted measureless suffering, to benefit themselves and their cronies. Plaintiff, in the utmost good faith, alleges that there is much evidence that this happened, or at the very least was allowed to happen, to further the defendants’ imperial aspirations and their monetary greed, and (as no one in government has done their duty to investigate, expose and prosecute these crimes) this lawsuit may be the only peaceable means to reveal the truth.

Well, not totally alone. This "hero" does have his lawyer to help him "reveal the truth".
