This really gets under my skin at some of these tournaments and other youth sporting events. Do not tell me it is just tough love. I have approached parents out of line and I have had parents tell me that they will do what they want to their child - I informed them that I felt different about some of those particular situations. I think it can be a class B misdemeaner if you know about repeated situations and you do not report it.
Child Abuse Law KSA 38-1522
Kansas State law states that whenever one has reason to suspect that a child has been injured as a result of physical, mental, or emotional abuse or neglect or sexual abuse, the person shall report the matter promptly (KSA 38-1522).
