Hitler disarmed the civil populations of every country he invaded. Those with firearm registration rules were the easiest to disarm. His decree that any jew could not own a weapon was simply an extension of the 1928 Weimar Republics gun control laws. Any delay in handing in weapons meant many were rounded up and killed just for a delay of one hour beyond the deadline for handing them in.

(one reason why your second ammendment should have been your first in my opinion)

It was not easy to obtain weapons but the WGU happened, further proof that such laws are unworkable. Remember the Auschwitz uprising too? One oven destroyed by the Jewish Sonder Kommando. (good work boys)
