Your discussion is pointless for the simple fact that it will have no outcome. It will change nothing, it will contribute with nothing, it will reach no conclusion. You're trying to discuss things that don't have a place to be discussed here, because they're meant to be discussed In Character. We could spend all day talking about what trespassing is, about who owns what, but it wouldn't change the fact that we will consider that buildings ours, and that we will protect our members. And unless a Game Master tells us to do otherwise, that is what will keep happening.
I'm not ranting, I'm trying to discuss. If my reasoning is pointless then show why it is by reasoning against it rather than just having it called stupid by a moderator. I am in no way trying to smear peoples perspective of the DE in anyway, I'm trying to argue the point against people breaking IC laws and nobody doing anything about it where as they would in other cases if the guild was openly breaking the law just because it is not imediatly obvious because there are no gaurds doing what gaurds would do.
That person obviously didn't call any guards. The place is in a sort of alley, so I doubt any guards would be nearby. That person was alone, it has no witnesses. So your point is? If you're telling us that, in this isolated incident in a back alley there should be a guard, and our member should have been punished... Well.. I think that's a rant. It's what you would like to have happened. It didn't happen though.
EDIT: It's pretty easy to say logic things and wish for them to have any relevance. It's actually not so easy to make it so. Either you come up with an Out Of Character, plausible reason, which discussion will bring about something useful for any of us, or you hush and look around for other threads where your opinion might have any weight.
