No one wants to confiscate your guns

Right up until they do.

From New Zealand:

The country has no national registry, making it incredibly difficult to track which weapons need to be bought back as previous gun laws did not require AR-15s to be entered into police databases, making it almost impossible to track how many exist and how many need to be bought back. More than 1.2 million guns are estimated to be in New Zealand.

I have never believed those who say that the purpose of registration is not to make confiscation easier and I have never believed those who claim that no one wants to confiscate guns in America.
