Why registration? What is gained by having a list of guns and owners?

40. I agree with you on 3 and 4 (and those are the reasons that a pro-registration person

would never say out loud anyway). Bus as for #1 and #2:

1) Anyone becoming a prohibited person should have recourse to the finding and prohibition. (Due process, etc.)

Yes of course, but that's beside the point of this topic. The question is what happens after someone becomes 'prohibited' via the legal process. And therefore,

Thus, an ample reason for a warrant to search your home and vehicles shouldn't be a problem. Shouldn't this be SOP for everyone on becoming a prohibited person?

absolutely not! There are reasons for becoming prohibited that in no way support probable cause for a search, and even those reasons that are criminal do not necessarily justify a search warrant, just on the chance that a person might be armed.

2) UBC enforcement would be no more effective than laws against stealing firearms. I infer that the objective of a UBC would be to prevent prohibited persons from gaining the possession of a gun. Enlisting the support of existing gun owners by making the UBC a free or nearly free exercise which could be conducted at a local law enforcement location on a voluntary basis would likely have better results than some heavy handed enforcement plan.

People obey laws for two reasons, I'd say: because it's the right thing to do, and fear of punishment. Registration would increase the likelihood that a non-BC transfer would be detected. And so, it would arguably increase the level of compliance with a UBC law (without interfering with any other methods to encourage compliance). And yes, it all should be free and easy.

So, I'd say that #1 and #2 are legitimate and positive reasons to support registration. Whether they justify the expense and effort of a registration system is rather doubtful, but that's not the question you asked...
