Every incident involving a gun has been committed by someone willing to ignore current gun laws.  How will more laws help?  Many of these crimes are committed by someone that doesn't own the gun used so background checks are not going to help the situation.  The old saying "If guns are outlawed, only outlaws will have guns" is truer than many want to think.  By the way, in the last 24 hours there have been several crimes (Texas incident to name one) committed with knives.  Are they next to be "controlled"?
