I had my first Justice happen in my tavern the other day. A human started fights with some folks. Didn't even end up sending anyone to the hospital zone. I convicted him of the first few counts, and he continued to try to pick fights even while the captain was thrashing him. Trying to thrash him. I didn't think the captain was supposed to be using lethal combat for a beating, but I'm sure I saw him bite some human teeth out.
Meanwhile, Dwarven Justice is totally fine with the literal pools of blood the taverngoers have been wallowing in since Spring. Some visitor speardwarf somehow pissed off a human maceman and his entire band of marksdwarves. This maceman's shooters would just pop their heads in the tavern, take a shot at the speardwarf, and duck back out. Blood everywhere. Blood and those little "broken bolt" marks, because they were actually very poor shots. Ugly. Eventually the fight spilled out into the fields, and even though the maceman had every single tooth in his head knocked out, the speardwarf was eventually killed. Filled an entire refuse stockpile with man-teeth, laid out like someone was trying to grow man-tooth-trees. Teeth, of course, can't fit in a bin. Idiot dwarves.
That whole maceman/speardwarf mess took like two seasons to resolve itself. While that was all going on, I very regretfully had to evacuate the tavernkeeper and all booze from the tavern. I don't mind the fights, but dwarves and elves kept trying to escape the fort by drinking themselves to death. Sorry gents, but it won't be THAT easy.
