If you are unfamiliar with Columbia there was this link below the Baltimore Sun story when I first saw it:
Columbia: 10th most perfect suburb?
This is the start of the Wikipedia Article about Columbia:
Columbia is a planned community comprising 10 self-contained villages, located in Howard County, Maryland, United States. It began with the idea that a city could enhance its residents' quality of life. Creator and developer James W. Rouse saw the new community in terms of human values, rather than merely economics and engineering. Opened in 1967, Columbia was intended to not only eliminate the inconveniences of then-current subdivision design, but also eliminate racial, religious, and class segregation.In other words, Columbia was supposed to be the perfect suburban space. A place which is family friendly and relatively crime free. It is a place where people move so they can raise families away from Urban problems.
Columbia proper consists only of that territory governed by the Columbia Association, but larger areas are included under its name by the U.S. Postal Service and the census. These include several other communities which predate Columbia, including Simpsonville, Atholton, and in the case of the census, Clarksville. The census-designated place had a population of 99,615 in 2010,[4] making it the most populous community in Maryland after Baltimore.[5]
In other words, this shit ain't supposed to happen in places like Columbia.
But, it does, it can happen anywhere. That's what this shooting should hit home to you, but I know that you are a little too biased to believe the bullshit you spout without criticism.
Do guns really make people safer? If that is the case, why are these incidents so common in the US, but not other developed nations? Why not let the research speak for itself rather than silence it?
It's nice to say things, but not when objective facts contradict them.
