Taking a swipe at South Australian Attorney-General Michael Atkinson, who unsuccessfully sought "in a ham-fisted and unsuccessful way" to censor political bloggers earlier this year in the lead up to the state's March 20 election.

But advocates for an R18+ adult computer games category will be disappointed. Mr Hockey is the most senior Coalition parliamentarian to address the issue directly - and he expressed deep concerns about the linkages between violence in computer games and violence in society.
"I don't mean to suggest that there is no room for government intervention and regulation," Mr Hockey said. "There is probably a legitimate debate to be had about the controls (for example via the classification system) placed on extremely violent video games."
