I'm sort of a new character, only been playing for 2 1/2 weeks now. During that time, I've managed to make a living and had recently started to thrive due to getting 360% LP gains and figuring out how to hunt boars and bears effectively. I own a decent plot of land near a river, but I have yet to surround it by palisades (my fault, mainly). I logged on this afternoon to find many of my empty crates gone. Then I go into my 'storage house' to find my two Raw Bear Hides gone, along with well over half of my uncooked meat and some other miscellany. Clearly I've been robbed, so I decided to learn Ranging. I managed to both find Reek of Theft and, after much wandering, find the thief's house (
Picture). I'm pretty sure the carts there contain my stolen items, or at least someone else's.
So... what should I do? I have absolutely no clue whether or not I could win in a fight if I got Rage, my Strength is only 20 so I can't break through with a battering ram to get to the items, and I don't want to try getting Trespassing and poking around quite yet and thus leave my own trespassing scent. Any help is appreciated.

Edit: Right! Forgot! If I -am- confronted by this guy, would I be justified in killing him, or at least trying to? Or should I just demand my items back and get laughed at? In my eyes, this guy is a parasite, leeching off other people's hard work for his own benefit, but I don't know what the community thinks of this.
