The aftershocks of 9/11 and the ubiquitous ’war on terror’ have given new licence to censors of all stripes; ’national security’ is once again invoked to justify the clipping of the coinage of civil liberties, while the rise of various forms of religious extremism is inhibiting some people’s willingness to speak their minds.  Censorship has not only not gone away, it is taking on new forms.
