Suggesting gang violence doesn't effect the public is a wildly inaccurate and baseless claim. Too often innocent people are victims of stray bullets ect. And it's impossible to quantify the fear that people who live in gang ridden areas are subjected to on a daily basis or the negative economic impact felt on an area by scaring away people who can afford to leave.
I'm a resident of metro Atlanta and frequent the downtown area and have worked in communities where gang violence is a real problem. There are real, innocent, people who are victims of gang violence everyday. I urge you to not ignore or disregard this type of behavior.
Also, not to make light of the situation if this is a "legitimate school shooting" but over the past ten years I have spent literally zero minuets of my life in an elementary school, but quite a significant amount in gang occupied areas. Should I not care about violence in public schools because it doesn't effect me?
