Which is nationalized registration. A “list” for confiscation. One thing to have criminal/mental health data bases, quite another a “book of lists” for the socialist apparat to have access to, and just as in Cuba, for round up all the owners and their firearms.
In Cuba, it was Batista’s police registration that was used by the Communists to execute those owners who would not or could not give up guns they either had or had long ago transferred. A good friend saw his father shot in the head— on the street in Havana, by Che’— because he told him -
“there are no guns here” . But Che’ had the list. Truth was, the guns weren’t there- they were under a cabin floor in the mountains, and were later used against Castro- to no avail.
