Perter Collins 'has' lost something. His previous 'fame' as an angler/angling journalist has now turned to notoriety. Many anglers who otherwise would heve respected him will now no longer do so.
What we have here is an 80 year old man, maybe getting a bit doddery, with a bee in his bonnet about zander. Much as we anglers might decry his crime, on the scale of criminality it barely registers. An 80 year old who commits a minor crime like this is pretty much immune against the law. Fine him? Suppose he refuses to pay, are you then going to lock him up? They don't even (well hardly ever) lock up ex-nazi war criminals. I think the EA got it right. I think they were almost compelled to come to the decision they did. To have done more would have, potentially, opened the way for a lot of grief to fall on their heads - expecially if it was shown (and there are plenty of clever lawyers) that Peter's mentis wasn't fully compos.
