Some history on the Hitler confiscated guns when he came to power.

During a speech in 1942, Adolf Hitler said, "The most foolish mistake we could possibly make would be to allow the subject races to posses arms." In other words, Jews and others whom Hitler wanted to wipe from the earth first had to be separated from their guns.
When Adolf Hitler came to power in 1933, he seized gun registration information that had been compiled by Germany's previous government under the premise that the information would not fall into the wrong hands or be used for an all-out confiscation scheme.
Sort of sounds like the old story of govt needing to "protect" us.
