I am sure that most players in this sorry saga have well and truly gone to ground. In doing so, should they have been involved in dubious actions, such activities and elements which were unacceptable or controversial will have been sanitised.
Future legal jurisprudence has many elements which need to come together to resolve what happened. It may never occur and even when it does much of this will be history and will not have the media impact that this episode has courted.
At best it may cause the relevant authorities to review and change legislation but as someone alluded to they do not have the finances or staff. Furthermore we may have left the EU by then which might also impact on this resolution of this tragedy.
