C-diggins, I notice that your angle of logic is not on the "trespassing" issue. And instead is on the "taking" (aka "stealing") aspect of pinching a coin off some corporation's ag. crop field. Very interesting.
Because technically, you're right : Taking that coin from the row crops is *technically* "stealing". But let me ask you a question: Although what you're saying is technically true, But do you see a difference in the following:
If you went over to that corporation head's house, went over to his night-stand, and "took" (ie.: "stole") a dime or gold ring off his nightstand. Versus a dime or gold ring in a field. Technically the answer is that both are identical. Even though the corp. owner MAY INDEED know he's now missing his gold ring or dime, versus the one in the field that had been there for 100 yrs, that he DIDN'T know was "missing" (in fact, he never even knew it was there). I don't know why, but for some reason, people tend to see a difference between something that is unknown, versus that-which-was-known. Even though technically, in the eyes of the law, there is no difference.
Or put another way, if we start down this path of logic, then so too would we have to conclude that by taking (ie.: stealing) coins from a park or a school yard are equally illegal. Because there is always laws on-the-books which forbid "harvest", "remove", "take", of any park feature. Obviously the rules are so that no one thinks he can start harvesting the sod for use in his own garden. Or taking home the park benches etc... But there is no technical reason why the same rules can't apply to individual fumble fingers coins. Yet ....... if you look around you, you see scores of posts of people who "take" (aka steal) coins from public places.
Why ? Because deep down inside, we all subconsciously know there is a difference because that item in the ground was un-known, lost, etc... Ie.: as if it DIDN'T "exist" till it was brought to the surface. Is that technically defensible ? No. But just sayin' that if you start down that path of definitions, is the day you can like-wise cease detecting all forms of public land as well.
