Last year at least 278 children unintentionally fired a gun and injured or killed someone. Kids such as the 5-year-old in Missouri who was playing with his grandfather's handgun when he fired it, killing his infant brother. Or the 3-year-old Ohio boy who found his mother's handgun in her purse and discharged it into his own chest. Or the 4-year-old son of an Alaskan state trooper, who found his dad's personal weapon and was looking down the barrel when it went off.
In isolation these tragedies seem like random accidents, but together they form a pattern — one we can interrupt if we track the data and test the most promising solutions.
