I think there's a legal doctrine along the lines of "open door" or "unenforced property", wherein if a person does not put up a minimum standard of defense of their property, there are limitations to what legal protection they have against trespassing and theft. For example, if I leave my house with the doors wide open, all the time, I think the doctrine means I can't accuse people of breaking in if they simply walk in ... especially if they do so repeatedly without me doing anything to stop it. Similar if my property has no fence, gate, locks, etc and people are in the habit of walking across it - and I haven't taken ordinary measures to stop them - then I can't accuse people of trespassing. The examples are not great, and I don't recall what it's called ... but I believe there's a legal doctrine along those lines. Oh, and, IANAL.
