Hasn't worked? That is a bold face lie, considering European Union as a whole has gun deaths a tenth of our 10.6 per 100,000, at only 0.9 per 100,000. Gun violence in the EU is the rare event BECAUSE OF GUN CONTROL. Whereas in our country it's a daily occurrence with mass shootings seemingly every couple of weeks at least. It's been shown time and time again that gun violence is purely a result of our lax gun control measures.
