“Sacramento police arrested a man Friday, after he and an acquaintance showed up at the hospital with gunshot wounds,” sacbe.com reports. “Police were called to UC Davis Medical Center around 3:30 p.m. after the two men showed up with non-life threatening wounds. Police say Gregory Carlton Walker, 53, made an illegal, homemade gun [not shown] and shot himself and his acquaintance. Walker has been jailed, with bail set at $60,000.” I’m not sure that the gentlemen involved with this incident (filed in “violent crime” by the sacbe) were criminals before they violated California gun law, but clock the wider point. Ban guns, confiscate as many as you can, and the bad guys will still have them. Would doing so at least reduce crime? I have one word for that: Mexico.
