Apparently you have forgotten that McViegh claimed that the military placed a chip inside him while he was enlisted. That should easily meet the definition of someone who may not be in full control of their facilities.
Whats interesting to me about this is that the Iraqi's may have been trying to get our government and the general public to trash militia groups and the extreme right wingers. That is clearly a diabolical and very clever way of beginning to divide a great nation that they were at war with. It is also apparent that they have acquired sympathetic individuals within this country to attempt to cover-up thier clever 'divide and conquer' strategy. Unfortunately however they over stepped their bounds when they destroyed the WTC and attacked the Pentagon. The Iraqi's and their allies cannot even handle the small nation of Israel and all they have done by attacking us is to unlesh a giant that is at least 10 times as powerful as Israel. They have sealed their own fate.
