Thanks to the contributor who sent in these images. This dead eagle was found on a Scottish grouse moor in 2010. Tests showed it had been poisoned with a banned pesticide. Nobody has been charged.
It seems that unless the poisoner is actually seen placing the bait AND unless the eagle is actually seen eating from that bait (how unlikely is that?!) a prosecution will not be forthcoming. We know from experience that even with filmed evidence of illegal activities a prosecution is not guaranteed. This ludicrous situation sends a clear message to the poisoners: carry on, you are immune from prosecution.

A photo like that sends a shiver up the spine…if the dog, or a child have found that corpse first…?!..on the danger point alone our authorities, from government funded analysts to police to the Crown Office, should be ensuring that the exact locations of these crimes are published and clearly accessible to all who might be put at risk – published in local papers, published in official reports available to the whole of the public and our political representatives.
Sorry Dave, while I agree totally with what you’re saying it will never happen, simply because that would upset the status quo and make it extremely difficult for the estate owners and their gamekeepers to do what they do best! That is to murder our rare wildlife and get away with it scot free, thereby ensuring the least publicity for our peers of the realm and their cohorts as they go about the business of shooting large numbers of tame pheasants, partridge and semi tame grouse.
