yer a good german jc, i'll give you that
but you allowed yourself to get suckered into the hype and since you don't have the conceptual skills to think your way out, i'll throw you a bone:
9/11 didn't happen because there was no Patriot Act or war on terror. it didn't happen coz there may be "sleeper cells" or coz we didn't know about Al Queda or comprehend the threat. it didn't happen coz the Feds didn't have the power to detain people indefinitely, charge people with laws too secret to make public, or search their book buying habits.
in short, 9/11 didn't happen because of some great revelation we have only now come to realize.....
9/11 only happened because basic existing functions of government failed; specifically immigration and airport security (as overseen by the FAA).
remember that JC, and perhaps you'll be able to frame a coherent line of thought on this subject in the future.
