It saddens me when I read stories like this so called hunters,trappers bushcrafters have got to keep in mind the responsibilities that go with all of the above, in this case it could have been a unfortunate accident, but rule off thumb all traps must be checked at regular intervals and all traps must conform to latest regulations and recommendations by DEFRA and the law if in doubt don't use them simple as that, trapping is far harder to monitor than a bullet as the bullet is in the now and you know there and then if you have caused a humane kill or need to follow it up to dispatch your quarry traps are totally indiscriminate and do not select species
