ich - // How do you know the investigation is ridiculous? //
It is ridiculous for the reasons I have already outlined.
By definition, if you investigate somethimg, it is because you want to know more about something, to discover something that you didn;t know before, and see if that helps you to reach a decision about what you do next.
Exactly what does anyone - and I'll ask you, since you are posing the question about its validity - do you possibly think is going to be 'uncovered' by an investigation by a load of suits who know a wholte lot about cricket, and probably very little about investigation - how to do it, what to look for, and what to do with what they find, if anything, which I very much doubt.
There will be an interval of time while this young man is pilloried in the press for youtfhul stupidity, a loads of suits will wonder what to do next, then they'll say something about 'lessons being learned' - and he will get his job back.
Watch this space.
