by Mark H. Gaffney, The Unz Review:
Skeptics have pointed to the alleged absence of radiation at ground zero as proof that nuclear weapons were not used to demolish the twin towers in New York City on September 11, 2001. This argument, however, is a logical fallacy that can never rise to the level of proof because the alleged absence of radiation is not evidence of its absence. Such thinking is a red herring that, unfortunately, has set back the cause of 9/11 truth by many years. The subject of nukes has been taboo within the 9/11 truth community ever since Dr Steven Jones posted his 2007 letter at the Journal of 911 Studies.
