Registration is a necessary prerequisite to confiscation.
We have one glaring example in recent history of random door to door confiscation of unregistered guns - New Orleans PD in the wake of Hurricane Katrina. Google the vids, it is truly shocking as in “not in my America!!” fashion.
Now, New Orleans is a uniquely corrupt American city. The Katrina raids were against white homes. That’s all that needs to be known.
Ordinary citizens may have to develop a tolerance for cutting angry flesh.
