I have encountered the lone gunmen only sporadically of truther websites but and have never seen it used by so called reliable sources I have mostly seen the Lone Gunmen used on weird coincidences type articles It would not strain credulity that as the President s brother even though he left the company Marvin Bush still had influence or that he intentionally left the company a year early to cover his tracks And if a domestic terrorist plan got as far as approval by the Joint Chiefs of Staff a domestic terrorism plan may have gotten approved by the a later President or Vice President What there is not is any proof of is that Marvin Bush ordered explosives planted or in any way intentionally compromised security at the WTC or that a domestic terrorism plan was ordered by Bush or Cheney It is difficult to prove a negative so there is no hard proof that these conspiracies were not ordered That is why the arguments revolve around whether a controlled demolition happened Even if it could be conclusively proved that there was a controlled demolition there would be no proof of who ordered it An even if a controlled demolition did not happen that has no relevance as to whether a LIHOP conspiracy did or did not happen Be that as it may if you find verifiable information the the Lone Gunmen is an important truther argument add it to the article And Wikipedia is based on verifiability not truth Verified main arguments by truthers and debunkers need to be presented no matter how incredulous it seems to us
