I can never get why people chime in with “why now?” and “what purpose could it serve?”
There are a bunch of victims out there who have never had the truth told, for whatever reason. Maybe they were too scared, not believed, systematically discredited, or any combination of those things.
A perfectly good answer to “why bring this all out now” would, in my opinion, be “because it hasn’t happened yet”.
The same line was used about Hillsborough, the same answer applies.
