Dear Kilgore, there's been quite a number of cases in public mines with the following MO:
1. asshole 1 enters a mine with a HKp90c or similar and checks the slaves' (making a honest slave work there) inventory for stuff
2. asshole 1 bursts the slave, gets killed by JT guards (mark that TJ guards forget about asshole 1 later on, they don't keep records on the fucking bastard and allow him to enter the mine again armed)
3. asshole 2 (either a friend or an alt of asshole 1) enters the premises with a brahmin or a follower and just CTRL +Gs all of the dead slave's ore, trades with the cow or a follower putting the stuff in their inventory, walks away, ROFLs
I don't think that has anything to do with common sense or the game's logic.
I think guards should either weapons check every PC and take the weapons from them like in New Reno or remember the guy who killed an innocent slave in the mine, or both, UNLESS they are all killed, so there's no one alive to remember.
To sum it up, I don't have anything against mass attack on the mine, where every attacker fights with every guards till extinction. I only have a grudge against these goodfornothing fucking sorry asses who exploit the games system in the way mentioned. I move to propose the New Reno casino system to be implemented in public mines (put a fence around the damn thing, put a npc to converse on the entrance) OR maybe even better, that the guards auto attack the known offenders (a reputation system similar to towns), unless every single guard has been killed during that attack and there's no one to testify.
