SK: Actually, you’ve omitted a few key points, but they change the entire thrust of your argument. Yes, Hitler did expand gun ownership, but only for “citizens” and those it deemed friendly to the Nazi Party (NASDP members, for instance, were not required to have a permit).
Those who were not “citizens” (Jews fell into this category) and who were deemed enemies of the Party, were denied permits (or disarmed or imprisoned). The police forces, which were now under Hitler’s sway and included the Gestapo (Geheime Staats Polizei, or Secret State Police), now spent far less time investigating crimes and far more time investigating people, which included arbitrary disarmament of those inimical to the Nazi cause and jailing/imprisonment on trumped up charges.
In this case, it’s the context and the background that really counts.
