Bragg, you say:
"say that there was a law against it and I was ignorant to said law, but went about MD'ing and ran into an officer then the fact that I was ignorant of the law would not have been a suitable defense."
By all means, don't be ignorant of the potential that there might be a rule saying "no md'ing". I'm not advocating for anyone to not check (if they're skittish and wonder). That's not the issue at all here. No one here is advocating going and breaking a "no detecting" law, if one existed. I'm just wondering if you couldn't have availed yourself of that same info by looking it up yourself?
You did carefully word it I see, when you asked. You did not ask "can I metal detect?" (which risks putting you at the whims of an arbitrary "no", when/if no rule exists saying such a thing). Instead you asked: "are there any laws about metal detecting?" (so as to put the burden-of-proof on them to cite any law, if one existed, right?). The only fear I have about that improved way-of-wording, is they might STILL morph other things to apply. Like "harvesting and collecting" or "defacement", etc... (even though you never mentioned "dig" or mentioned you'd be taking "their" goodies, etc... it's just some people's natural image when they think of md'ing I guess). This has happened to folks even with the improved wording. And sadly, it can happen in places where detecting was never an issue for anyone up till then.
" I do not see the harm in simply contacting people to find out the laws that pertain to MD'ing in the area. "
If it was simply to find out if there were a "no detecting" law, I would agree. But as I say, I'd just be concerned that whomever you're asking can morph something else to apply. OR EVEN THIS : There's been cases where if there ISN'T a "law". And if the person you're asking catches the subtle clues that you intend to detect, unless they can cite a law. Well then guess what they do?? They bring it up at the next counsel meeting that "we need to have a law". YUP, this has actually happened. Laws invented to "address your pressing issue" ! I have the links to several such incidents, if you doubt that this can happen.
But you can satisfy your urge to talk to a live person, by instead asking them in this way: "where can I find the listing of all this entities rules, laws, and codes, available for public to view?". Then once they give you that link, or bring out the binder for you to look at, then you can merely answer your own question, by looking to and fro in said-listings for any mention made of "metal detectors" or "metal detecting". Afterall, that's the answer you were seeking from them in the first place, right?
