Britain, Canada, and Germany's Weimar Republic followed a similar path. The State always seeks to increase its power over the citizens. When gun owners are registered, it's only a matter of time before their civil liberties to bear arms are stripped of them. But that's an argument for the long-term. Disarmament advocates frequently claim that background checks stop X number of criminals from buying a gun, but that's false.
Criminals merely resort to theft or the black market to get guns.
But many honest people are left defenseless. Background registration checks especially hurt the poor, who lack both the funds to pay for the added costs of the checks and the legal expertise to prove themselves innocent to CBI if they are wrongfully denied. But poor people in high-crime areas most urgently need firearms to defend their families. But anti-gun politicians seem to care about neither civil liberties nor the poor. Contrary to phrases made popular by gun-grabbing politicians, background registration checks are UNreasonable laws that empower criminals and endanger the lives of children.
