Sad. It illustrates a truth about heritage protection that no-one likes to admit - it's not what the law says but what those responsible actually DO (or don't).
The French have it wrong too. Metal detecting there is entirely illegal yet they have more of them than us. Pourquoi? Because the law says only metal detecting for historic artefacts is illegal. So every week thousands of people are out on archaeological sites, every one of them searching for their lost car keys....
