Ok, first thing that pops into my head: Why are they meeting in a one-room building but unarmed? Usually, the types of meetings that go on in one-room buildings are a bit less than totally kosher, so it seems unlikely that they’d really be unarmed and weaponless. Second thing: When you say standing their ground, what does that entail? Talking them down? Trying to reason with them? Appeal to their good nature? Tell them that they can’t take down the entire group, and whoever survives will tell on them to their mommies?
