This map displays the casualties and fatalities in school shootings in the US from 1997-2012. It is based on data drawn from the Brady Center to Prevent Gun Violence.
This is not a great chart — the size of the circles creates a perceptual problem (each school shooting doesnt cover a 200 square mile area) and the coloring of the legend is not at all intuitive (wait is purple good or bad?) — but even with that, the sheer volume of School Shootings surprised me.
Please use the comments to demonstrate your own ignorance, unfamiliarity with empirical data and lack of respect for scientific knowledge. Be sure to create straw men and argue against things I have neither said nor implied. If you could repeat previously discredited memes or steer the conversation into irrelevant, off topic discussions, it would be appreciated. Lastly, kindly forgo all civility in your discourse . . . you are, after all, anonymous.
