Define children. I've seen some definitions up to ages in their 20s. The same stories where we post and give high fives to each other for some scumbag robber ending up with lead rather than money, these people will chalk up as "another tragic death of a child killed by an gun". They probably even count some tragic military training accidents as children dying from guns in their definition.
ABC’s other story about “kids” finding guns and playing with them actually involved college-aged adults.
And gang bangers shooting each other.
