First off--Well Said, dahut.
I agree with you about the "altruistic oatmeal." I have a strong conscience and even stronger convictions when it comes to MDing...and I recall that when I started it was about the history for me, but it was never about "saving" anything. It was about Discovering something in the ground that was Lost before I did what it took to find it--and it was about Discovering something in myself as well... Of course, I was 13 then and things are a little more complicated now.
I think back then I could've said "saving history" and believed it. But now, there is a nagging suspicion that it isn't true. It has bothered me and eaten at me for a long time now, and you touched on it in your reply above. This is part of the reason I don't sell finds but once in a blue moon--I feel that when money is involved, part of the Good things in the hobby fade (and at that point, I'd know that the Altruism would be more than an exaggeration--it'd be Fake). If it is Hoarded, is it "saved"? If it is Sold, is it any more, or less "saved"? Good questions! I have hunted with folks that dug just with the intent of selling, and it is not an experience that I enjoyed, and they were folks that I knew would, as you put it, stampede over me in a heartbeat to get at something of value.
You're right. We do need a measuring stick for how well we're doing. Since the internet, my ideas about what was a good hunt have changed--but I've also had many benefits in terms of information, techniques, and identification of finds. But that is a topic for ten pages of replies at some point in the future...
Value. Quantity. Quality. Most of us set personal goals to recover something Valuable, to find More of X or Y than we found last year, or to find a higher grade item than the one we already have. And while these are all good for bragging rights, they are external values. And I can say without any of the Oatmeal that part of the value of a hunt comes from an Internal scale of worth for me. Not all relics and coins can be found in places where I can see Beauty in the location around me--so I treasure items that were found in a beautiful spot. Not many of my recoveries can be made with my father anymore, so I value items found on hunts with him highly. These are just two examples of internal "worth." To corroborate my claims, I will say that I have sensed this value system on TreasureNet as well--when someone hunts with their family, or parents, there are frequently as many or more replies to their post as there are when that person finds an object of great monetary or historical value. I would personally like to see one of Those posts make the Banner sometime!
So the "value" (what a problematic word for the Philosophers as well as us everyday Joes)...the "value" of an item is hard to gauge. And unless folks can communicate in writing the value they place on the hunt, the scenery, an easy (or difficult) recovery, good companionship, family, or tradition...this sense of Value goes unnoticed in posts on this and other Internet Forums.
The Law is blind to value like this. Try to insure a watch given to you by your grandfather. How much is it worth? And quite possibly, we detectorists (some, but not all) use a different system of value from the system used by Archaeologists, State and Local Governments, etc. What is of Historical Value? I keep a LARGE display of suspender clips. What are those worth? Will they clad me in irons and take me away for having them?
I regularly do presentations at local schools on "Life in the 1800s" and talk about MDing and show items I have found that have a story to tell. I figure that the way to counter Negative publicity is with Positive publicity. And every time I show that display case of suspender clips, and see the smiles and wide-eyed expressions on the kids' faces, those clips get More "Valuable."

So I figure if history cannot be "saved," it can at least be Shared.
So before I get totally off-base here... back to our situation in the West Bank.
Sounds like the problem is the fact that the government there can't put any "teeth" behind the laws that are in place--in terms of both punishment for offenders and police force itself.
A law is worthless unless it is enforced.
It is almost funny--and scary as well--the lead photo. I agree with you that the implications of the photo psychologically are worse than any negative publicity in print in the article itself. This is in light of the last eight years, especially.
We do not have such laws here for the most part, excepting areas that are nationally or locally protected. And on those protected areas, night hawking is still a problem here--but folks here do not use bulldozers to accomplish it! Sometimes it is even the park rangers themselves that illegally recover. (Oops. Did I say that out loud?)
I do agree that the tendrils of such an article touch on all of us, since detectors are mentioned in a negative way--but we're talking about areas there of World Cultural Heritage and Significance--not parks, beaches, and yards like we hunt here. So I think it comes to this: Can the general public who read this article make the distinction? Probably not. And that is the problem.
Best Wishes,
