20 People left alive--why do some of them have to be jerks?

Just when I thought things were settling down a bit, we get two idiots who risk the whole group. Geoff and Cynthia decided to leave early this morning, before most of us were up, and the A-holes took 3 guns and a bunch of our food with them! Matt spotted them from the roof--he didn't know what they took or he probably would have popped them right there. There was no time for a discussion or a vote or anything--when we saw the guns missing, we formed up a posse and they went after them. Matt, Shawn, Corey and Jacob went out right on their trail. I wanted to go with them, but then again, I didn't. I mean killing zombies is one thing, but what the heck are we supposed to do with these folks? They're just ordinary people, a young couple, right? Except they're armed, armed with guns they stole from us. If I went along, I would be the cooler head who is supposed to prevail--the problem is I don't feel very cool right now, and even if I was, I don't think Matt is going to be in any mood to negotiate (Shawn either for that matter--he has kind of become keeper of the food and he's taking this theft personally, too). They're coming back with those guns and food, no matter what, and I guess I'd just as soon not know what the "No matter what" is.
