Over 500 kids have died from gun violence since Sandy Hook.

In the three years since Adam Lanza killed 20 children and 6 adults on December 14, 2012 in a school in Newtown, Connecticut, at least 554 children under the age of 12 have died by gunfire, according to an NBC News analysis

In other words, an American child is shot and killed at a rate of one every other day.

Hovering over each dot brings out a different tragedy: There’s 4-year-old Makayla Menners (Yonkers, New York, May 25, 2015). 10-year-old Elvira Campos (Sacramento, California, May 18, 2013). 21-week-old Kaden Hiatt (Jacksonville, Florida, November 14, 2015).

Seems like a good an argument as any to ban guns entirely, as Phoebe Maltz Bovy argued last week.
