When all the guns are controlled by the government will we all REALLY be safer?

Yes... I stand corrected, but it's correct only if you were not a Jew.
The 1938 Regulations Against Jews' Possession of Weapons, promulgated the day after Kristallnacht, effectively deprived all Jews living under the Third Reich of the right to possess any form of weapons including truncheons, knives, or firearms and ammunition. Before that, some police forces used the pre-existing "trustworthiness" clause to disarm Jews on the basis that "the Jewish population 'cannot be regarded as trustworthy'".

Well, yeah, but that's because... You know... Nazis.
