Darkspilver. I can even see where it can be even more complicated let's look at just the US for congregations that maybe on a border of a state or a foreign language congregation that has members in different states but meeting in the same congregation. Each state would have their own laws and it would depend on where the act took place and that is how the law would determine things.
Even in Europe where it is common for people to travel quite frequently to other countries within the union if the offense took place in one country where it might be legal for that to have occurred but was reported in another country where the age of consent is higher. How do you deal with a situation like that?
