Not sure we can get into this discussion, at least in this thread, but it seems plausible particularly given that there was already a civil case closed with an NDA in place.
Must be hard to investigate fully, not to mention we are now 5 years past?
HC mentioned a while back that the NDA was cracked open, presumably due to political and subsequent public pressure, that and leadership change. I don’t think that agreement holds any sway any more.
The London police did say that there is enough evidence to conclude that an assault did take place (or something to that effect) however, in these types of cases that’s very different from also concluding that there is enough evidence that a ‘crime’ was committed (mens rea). Prosecutors while have to decide if there is enough evidence to prove guilty mind, because the guilty act is not being questioned.
I suspect that there is a huge question of whether it is to the public benefit to make public the names of several people who will be most certainly judged by the public regardless, without strong enough evidence to secure a legal guilty verdict.
