Of course there needs to be an investigation into what the BBC tolerated on BBC premises. There is also the need for a proper review of what happened at Haut de la Garenne and the allegations of abuse cruises off Jersey.
However, it should be noted that (only last year) the UKBA banned a journalist (Leah McGrath Goodman) from the UK and Jersey who wished to investigate and report on what happened at Haut de la Garenne. She still does not have a visa to allow her into Jersey.
The first thing to do, therefore, is to allow Leah McGrath Goodman into the country. I am surprised that the journalistic profession has been so unconcerned about the banning of a journalist from the UK.
