Somewhat ironic...
...that your article should itself succumb to the loaded use of language it's reporting as problematic:
"links directly to 9/11 conspiracy theorists"
Who are they then? There are many theories and hypotheses about 9/11, some bonkers, some worthy of investigation, some official, some conspiratorial and absolutely *none* of them proven anywhere near beyond reasonable doubt, most definitely including the official ones. Indeed there is a fair body of perfectly intelligent, logical people who would suggest that it is not in the US gov't interests to prove their hypothesis beyond reasonable doubt - they certainly display no signs of wishing to do so, five and a half years on.
