There are all sorts of strands to the Savile cases, but one remains hidden or not followed, and that is the one of the facilitators.
Some people have already claimed that they "knew" what was going on... they have even gone public with their claims. So, why have none of these people been arrested?
If they really did "know", and did nothing, they are as guilty as the perpetrators. If they are doing nothing more than passing on rumours then they are guilty of wasting police time. Either way they need to be reigned in.
