Ts1969,
Maybe more will be written if there are convictions, but if the Watchtower wiggles out of it there won't be much to report. As you say, private prosecutions are often not taken seriously; probably because most don't have enough merit. If the prosecutors take this case over from Unthank it will be a big step forward.
I think most of us on this site are hoping for convictions and news coverage eventually. The case deserves it.
Oz makes a good point, it's just Jehovah's Witnesses, a small religious group in the world. If a reporting agency could aim the story more toward the child abuse angle, maybe it would sell. For us, we are looking at how bad the Watchtower is, but for the story to get the public's interest it might need to highlight the children's safety issues.
