I'm not one who exactly knows the laws in this specific area (I do know some law, but this is FAR from what I have been involved in), all I can relate is what I was told.
The abuse WAS real (or is I suppose, though I imagine the kids are in custody now [edit: stated this wrong, not custody, but taken by services that protect children and placed them somewhere safer]).
It is kind of surprising how people go into denial in regards to this type of stuff, even when it is right in front of them.
I find it also interesting the type of reaction to the update given.
I am currently considered a mandatory reporter apparently, and yes, apparently we CAN be charged with a crime if we do not report suspicion on such things. It can be a felony in our case.
As I said, I have not been charged yet (and I hope I will not be). It may just be the laws in my , but it is a crime not to report as I have found out. Any volunteer that provides organized activities for children at certain organizations or camps are considered mandatory reporters in my area.
I have not had contact with the two kids since that session, my update was based on the information from the player that reported the incident to their parents (and subsequently the police) and my own interview.
In retrospect I suppose I should have had a lawyer with me, but I didn't even think about doing that. They wanted to talk and I talked with them, it didn't even occur to me to bring a lawyer with me.
PS: After the interview with the police I did a little research to find out for myself if I really could be in trouble. I DID find this as well which does NOT make me feel any better of my actions nor my situation, though I feel that (or hope strongly) I won't have any legal action against me.
I did do some research into the matter, and I found out there are laws as such that I wasn't as aware of.
For example
Citation: Ann. Stat. § 39.201
Any person who knows or has reasonable cause to suspect that a child is abused, abandoned, or neglected by a parent, legal custodian, caregiver, or other person responsible for the child's welfare or that a child is in need of supervision and care and has no parent, legal custodian, or responsible adult relative immediately known and available to provide supervision and care shall report such knowledge or suspicion to the department.
Any person who knows or who has reasonable cause to suspect that a child is abused by an adult other than a parent, legal custodian, caregiver, or other person responsible for the child's welfare shall report such knowledge or suspicion to the department.
Any person who knows or has reasonable cause to suspect that a child is the victim of childhood sexual abuse or the victim of a known or suspected juvenile sexual offender shall report such knowledge or suspicion to the department.
Though to be honest, I'm not sure if what we saw there would be enforceable as a reasonable cause of suspicion or not (though I WAS suspicious which is one reason I brought it up here). However, I'm not sure what will happen next. I tried to do what was right, but that's not always a good defense.
