Trenton, N.J.: I am writing in response to the commentary “The conundrum of child kinship care” (op-ed, Dec. 13) and false assertions made regarding New Jersey’s child welfare system. The author, Naomi Schaefer Riley, suggested that the state was engaged in a campaign to divert children from entering the foster care system by placing them in informal, unlicensed homes with extended family members, a “shadow child welfare system.”
