HE Heritage Crime Confuse the Issue

HE feelgood heritage tweet of today:

#OperationChronos help us identify the #criminal minority using #metaldetecting equipment to steal from our past

If it is a "minority", when are we going to deal with the incomparably larger number of moral midget knowledge thieves who use metaldetecting equipment to steal knowledge about the past from the sites they trash in their unmitigated search for collectables for personal entertainment and profit? "Grey detectorists" cause greater damage than the so-called "black sheep". Why isn't HE spelling out that message?
