And just who gets to determine who is allowed to exercise their God given right and who doesn't? The government? You? If you have to ask the government's permission to do something, then it isn't a right any more, it's a privilege, and privileges can be revoked at any time for any reason (or no reason - just the whim of a pompous "we take this very seriously" bureaucrat).
Gun confiscations have always been preceeded by registration. Even in the good ol' USA. NYC forced owners of semi-autos to register them in 1976, and then in 1999 confiscated them. To think that registration will prevent criminals from getting firearms is extremely foolish. Registration will not prevent criminals from obtaining firearms, and is not intended to prevent criminals from getting firearms. It's purpose is solely to allow the government to (unconstitutionally) keep track of the firearms of law abiding citizens for eventual confiscation.
