For a while, it was on 34.2.  It was originally a CBS show.   Person of Interest was the title.  I never watched it so I am just going off show descriptions and trailers.
The only problem I have with full registration is that it tells the government where to start looking for guns if they decide to confiscate all the guns and go rogue.  I agree that there are times when it would be good to have the government know where to look for the guns, but I also want to have some protection from the government going rogue.
