I have no doubt the matter is being investigated and if any crimes were committed they will be prosecuted and no doubt the items recovered will be returned to the UK MoD in due course.
Now as to the use of the word "Troops"....how many are we talking about that are actually culpable?
I also recall US Troops attending to abandoned British Cemeteries in other locations over the years.....so lets be even handed shall we.
There are two British Cemeteries quite close by where I live currently that are maintained by our Coast Guard troops stationed on the same Islands where the bodies of RN crew were buried during WWII.
Museums are full of items retrieved from old battlefields, tombs, and gravesites.
