Actions presumed unreasonable
Washington RCW 9A.16.100: It is the policy of this state to protect children from assault and abuse and to encourage parents, teachers, and their authorized agents to use methods of correction and restraint of children that are not dangerous to the children. However, the physical discipline of a child is not unlawful when it is reasonable and moderate and is inflicted by a parent, teacher, or guardian for purposes of restraining or correcting the child. Any use of force on a child by any other person is unlawful unless it is reasonable and moderate and is authorized in advance by the child’s parent or guardian for purposes of restraining or correcting the child. The following actions are presumed unreasonable when used to correct or restrain a child: (1) Throwing, kicking, burning, or cutting a child; (2) striking a child with a closed fist; (3) shaking a child under age three; (4) interfering with a child’s breathing; (5) threatening a child with a deadly weapon; or (6) doing any other act that is likely to cause and which does cause bodily harm greater than transient pain or minor temporary marks. The age, size, and condition of the child and the location of the injury shall be considered when determining whether the bodily harm is reasonable or moderate. This list is illustrative of unreasonable actions and is not intended to be exclusive.
Idaho Code 18-1501: Any person who, under circumstances or conditions likely to produce great bodily harm or death, willfully causes or permits any child to suffer, or inflicts thereon unjustifiable physical pain or mental suffering, or having the care or custody of any child, willfully causes or permits the person or health of such child to be injured, or willfully causes or permits such child to be placed in such situation that its person or health is endangered, is punishable by imprisonment in the county jail not exceeding one (1) year, or in the state prison for not less than one (1) year nor more than ten (10) years.
