No Law Suit?

Lots of people like me are now saying the Twin Towers and Building Number Seven were blown up. Although I have not named any conspirators many people have. If somebody said I did such a dastardly act I'd sue them in Court for every penny they had. I wonder why no one has sued for defamation of character yet? Could it be that the evidence could not support a building falling through itself at the same speed it freely falls to earth?
