I am not Roman Catholic but have studied comparitive religions for over thirty years and it may have been a way for Charlie to clear his guilt, but it was not a "confession" that would have any absolutoin power. A Roman confession has to be to a preist who has been given permission from a local Bishop to forgive sins.
Even a preist who is on vacation in France who is normally in Chicago can not simply fill in and hear confession while in Paris.
I'm not pulling your leg.
