This is getting quite absured!
If the alleged crimes are important then they require prompt criminal investigations. The remit must be broad enough to assure that relevant further criminal activities can be investigated without it turning into a continuous fishing expedition. It should be executed expeditiously and reported fully if it is determined to be in the public interest to know who the players are (in this context, not just footballers but investigators and those who engaged their services).
At the moment The Police look like the Keystone Cops and the media/Newspapers - the lot of them from the tabloids through to the broadsheets and the periodicals - look like a bunch of sleazy lizards. In fact they give lizards and keystone cops a bad name!
At the end of all this - in about 12 months, please! - when malefactors are guests of Her Majesty and the media companies have been exposed, fined and put under control New legislation to properly protect information that has no public interest needs to be put in place with adequately deterrent penalties included.
It wont happen, mind. Not while the great and the good worry about what has already been collected on them and what might just be exposed.....
In teh meantime it will be a lawyerfest...
