The Shootings You Don’t Hear About

There have been at least 180 shootings since the Orlando massacre on Sunday. Five of those shootings were considered mass shootings, when at least four people were shot in a single incident. One of those mass shootings was right here in California on Tuesday. A gunman opened fire on a vigil for two drowning victims. A 17-year-old girl was killed in that shooting. Three other people were injured. As we take a closer look at gun violence and how to prevent it, we ask about the killings that don't captivate the entire nation.
