Big Ruddock
Ironically Attorney-general Phillip Ruddock has led a new censorship drive starting with the TV show Big Brother, and extending through eight titles he has referred to "The Classification Review Board". They only agreed to censor two of them, so this is his justification for removing freedom of speech and enquiry.
Ruddock is upset that Terror Police raids in Sydney found nasty books. However it turned out that the books were legal, so no charges could be brought against these book-crimes.
Thus, the law must be changed to match Ruddock's views, and the Howard Regime have the power in both houses to do it, and the precedent of the 2005 Terror Laws.
