Yes the LEO's were doing daily pickups and getting daily drop offs of guns because the owners were now criminals and too afraid to keep them anymore.
My neighbour had a shotgun he bought from a private sale. When he became to blind to use it anymore he gave it to his son. A few years later the register was created, so he registered it. Two months late the RCMP showed up and took it away....told him it was on file as a stolen 12 yrs earlier. Lost his gun due to the registry.
