There is no need to retain a database of transfers in order to require background checks on all transfers. Here in California we had a law requiring long gun transfers to go through a dealer for decades with no state registration or database. We should not allow them to get away with establishing registration while calling it something else in order to pass it.
California does show very clearly where this will lead. Starting January 1st, we will have long gun registration here (handguns have been registered at time of transfer since 1923) - plus at least some of any number of new laws designed to make owning a gun as close to impossible as possible.
Right now, our hopes are basically limited to a veto of the worst bills by Gov. Brown (whom I would call "mildly pro-gun" - his record is decidedly mixed) AND finding at least 3 Dems who then will defect an refuse to override Brown's veto. After that, it's off to the courts.......
America, learn the lesson well: These people are NEVER satisfied. They will take every opportunity to pass more restrictive laws until you have no gun rights left.
