Because freedom:

A 4-year-old girl accidentally shot her 4-year-old cousin to death with a loaded rifle that she found under a bed at their grandfather's Detroit home.... "It's a tragic incident," Woody told The Associated Press. "It's really not anything more than that. There was no malicious intent. There was nothing there to suggest that the grandfather put those children in harm's way."

Leaving a loaded gun where children can find it doesn't meet the definition of putting "children in harms way"?
