For it to go to trial the job of the CPS and the defense lawyers is to get all of those who need to give evidence on the list submitted to the court before the trial starts, so naming a possibly innocent person in the press achieves nothing except aggravation for them and their family. I know of one person named in a rape trial who was hounded out of his home and dismissed from his job before the trial at which he was found not guilty and the woman who made the claims against him was later prosecuted for attempting to pervert the course of justice.
Agree, just saying I think thats why they name them.
