This. Canadas gun laws work. I own rifles, shotguns, and handguns, I love them. But I can't CC, I needed special courses for the handguns, and had to meet with a police psychologists, as well as be a member of a gun range. My guns need to be locked away, and nobody without proper licensing is allowed with them. (I can loan them to other license holder). We had two mass shootings in ten years, and two killings of 3-4 police officers each. I love my guns, but I also respect them.
