Forgive me—I am on my knees.
Having done this sort of thing, albeit in a relatively minor way, I want to clarify one thing. Often, information was given to people who were doing this kind of work in the field by juveniles. That does not make the juvenile a source. That information can still obviously be passed on, but clearly there are restrictions on using that juvenile in future. However, the information given by juveniles certainly must not be stopped.
