I consider not dealing with it when you have someone of of his stature being accused and them not raising the red flag to be a pretty poor show. Maybe we'll have to agree to differ on that.
The BBC has 23,000 employees. They receive hundreds of complaints a day about their staff, most of which are from cranks and nutters upset that Gary Lineker tweeted something wrong or Doctor Who is too woke.
I think if you expect any organisation that size to filter out the serious complaints from the trivial, then open and conclude an investigation in less than 2 months then you've got no idea how these things work.
