There has been considerable discussion (debate, flamewars) about gun control in the wake of the tragic shooting in Newton, Conn. -- so much that the NRA hid its Facebook page to avoid hosting flame wars.
It is hard for me not to be reminded of the debates about computer control while listening to all the debates on gun control. (See: Protecting the property, privacy and other rights of owners: Bill C-19 and Bill C-11 , The long computer registry and IT control).
No reasonable person would ever claim a computer could be as dangerous as a gun, and the long-run registry recently abolished was only a registration. That said, debates around so-called "Technological Measures" in Canada and the USA suggest that Conservatives in Canada and Republicans in the USA consider computers to be more dangerous than guns. The USA and others continue to push computer control into various treaties, including within the Trans-Pacific Partnership (TPP).
Lawrence Lessig might suggest the differences are a case of corruption from money in politics than actual policy positions, but I'm not certain this is the case. I still worry that a majority of politicians (and possibly the general public) are still confused by the Harry Potter version of technological measures where books or other digital information can magically come alive and make decisions on their own. Too many believe that "copy control" is more than a marketing term, with some not even realizing we are talking about computer control whenever talking about "technological measures".
