What do you suggest as a trustworthy source? I'd put money on you not having read the article, either. You're giving off strong 'Stop the Count' vibes now.
Yes I have read the article.
There are actually numerous examples where suspects before arrest have been identified and the relative crime that has been committed.
If we are to take an extreme example we could look at Raul Moat. Mr Moat was identified as a suspect in a killing spree and people were warned to stay away from him. Mr Moat may have been entirely innocent and surely therefore should not be named at all. If he had been apprehended and pled not guilty would his trial not have been prejudiced.
The reason the police appear to be saying it was not revealed at the time is because it cannot be related to the original knife attack and was therefore a separate investigation which has only just concluded for pre trial.
They also made a statement their was "very low risk" to the public with the substance found. I assume even if it was extreme high risk the argument deployed here would still stand? Namely that the evidence could not be revealed as juries would be influenced (I am sure the fact we already know he is a knife wielding maniac would not influence anyone at all). So I guess people would have had to be poisoned so the individuals rights are protected. Good job the Salisbury poisoners were not Welsh.
