Senator BOB CARR (New South Wales—Minister for Foreign Affairs) (14:45): I do not know what can be done about paranoia and conspiracy theories that circulate in politics. I do not know whether it is possible to have a rational argument with people who believe in those propositions and I really would not devote much time to it. I know there are websites set up in Arabic by quite good agencies to puncture such conspiracy theories and to present the uncontested facts about events such as September 11. I would simply caution against guilt by association, however, and that anyone who has encountered someone who holds such absurd theories is, by association, guilty of holding them themselves.
