I don't think we can ever stop this. More gun laws will only stop people who follow the law, the criminal doesn't give a rip... Crime pays when the consequences are almost non-existent. Drugs are a big motivator for some of these shootings. Legal drugs or not. We have a serious drug problem and the liberals answer is 'safe injection sites'. Of course it is, but we can't be distracted by nonsensical solutions. There has got to be a better answer and it sure isn't passing more gun laws, or any other 'feel good' laws.  Not one law would have prevented what this turkey did. Not any that are on the books, or any that the left might pass in the future. They only make the law-creator 'feel' good, while stripping honest, law-abiders of their rights. Wrong!
