|Criminal artefact hunting in UK|
The lack of any mention in the video and notes under it suggests that these detectorists having recognized the traces of illegal artefact hunting activity at a protected site did not immediately and responsibly go to the proper authorities to report it. Probably they were afraid that if they did, the case would enter the statistics of 'unresolved cases of illegal artefact hunting', to appear in any survey and inform public opinion on the actual scale of this severe problem. And that is the last thing UK metal detectorists want...
