it depends on how it's handled saturnvista and on the ages, I think. Not saying I'm right here, just saying how I think we would handle it; yeah, it is a very different situation in that the man down the street is not a member of the family.
If it was a member of our family ... hmmm.
I suppose since we're talking about a situation here where the offender was directly in my family, I'd want and need to find out the situation as accurately as I could.
I don't know exactly what counts as 'indecent pictures' actually. If indecent pics consist of naked 15yo girls not doing much, that's one thing (they -are- still children so presumably a conviction could be based on that? I'd need to know, which I don't atm). If indecent pics consist of extreme hard core stuff or young children, that's different. I've got a feeling I could be flamed here, but to me there -is- a difference. I'd need to know what he was convicted exactly of because this area is so controversial that there is a great deal of misinformation and sometimes miscarriages of justice, both ways.
If it was the second sort of pictures, I'd want no further contact at all. That's the easy choice actually because the decision is clear cut.
If it was the first, it's oddly harder. Would going to a restaurant for a birthday be ok? Yeah, it probably would. Would it be okay to let the children go there alone? No.
I suppose in this sort of situation if there can be any positive way forward, the offender needs to acknowledge what they have done, not to sweep it under the carpet and to cooperate with the parents in order to have any role in the grandchildrens' life. If they are denying, minimizing or sweeping it under the carpet then it'd be time to step back completely. That would include not allowing birthday cards or email contact.
If contact was feasible, it wouldn't need discussing with the children at first, we'd just go to the meal (or whatever) and come home. If they started asking if they could go to granpa's, the answer would be no. No explanation when they are smaller. At around 9 - 10, if it was a member of our family I think I'd say No, you can't, I'll tell you why when you are older. At 15-16 I'd give them the truth.
I -think- that how the child would hear the explanation would depend on how old the child is.
The one thing that would immediately mean NC would be if Grandpa or Grandma started making comments like 'oh why don't you come over one afternoon or stay with us'. That would show me instantly that they could not be trusted because given the seriousness of the offense, you just can't start suggesting that unaccompanied children go there for an afternoon!
So it's a long and complex answer sorry, but yes, the guy at the end of the road really is a different situation from it being in the family.
