treasure_hunter, thanx for taking the time to find those instances, and post the links. Whenever a question like ring-finder gets posted (which I too have often asked), I am painfully aware that .... yes .... no doubt .... someone's going to find actual instances of guys getting roughed up for detecting. Heck, maybe even jail, fines, confiscations, and so forth.
However, each time I pose the question that ring-finder asks, I include the following: That any such instance that someone can find, of "arrests", "confiscations", "Jail", and so forth, would no doubt be: a) someone night-sneaking obvious historic monuments, or b) someone who can't take a warning. Look at each of your links, and you will see either or both of those aspects clearly there.
And let me clarify something: I suppose it's *possible* to even find a link/story of someone getting roughed up for truly not knowing (ignorance) with no warning, and immediate consequences. And to have that happen at innocuous forest or beach somewhere, that is NOT an "obvious historic monument". Yes, even an example like that might be found, if you looked long enough. However, SO TOO can I probably find an example of a motorist who got roughed up by an over-zealous cop (& jailed, fined, confiscated, etc...) for nothing but a tail-light out. There will ALWAYS be extreme examples of prosecutions. If we all guage our lives by "what if's" and "worst case scenarios", there will come a time when you won't even leave your front door in the morning! Afterall: your neighbor might get mad. Or a lion might attack you, etc....
I'm not sure if the OP meant to include such "obviouis historic monuments" as the people in your links (and silly things like "doing it for 4 years straight while running from rangers multiple times!") But based on examples of a "church yard next to a cemetary", then no, I too don't see any moral harm in that. But I guess it would depend on what church, and if that were an "obvious historic monument" (I mean, I suppose such a setting could be at Manassas and/or Gettysburg, and thus be a church that ... perhaps ... you don't want to be hunting at.
So it's on a case by case basis. But no, I will not interpret vague cultural heritage things to be interpretted to say "no metal detectors". I do not see any harm in hiking out 5 miles into the desert to hunt a stage stop, adobe site, watering hole, etc.... that we researched out.
