But since when do Arbites not punish people for murder? They're normal law enforcements, basically today's police. Only Grimdark.
Not exactly; The Adeptus Arbites are few and far in between on a planet; If a geniune Arbitrator is getting involved, in means something really serious is going on. However, there's a tendancy among authors to refer to any local law enforcement officer in 40k as an Abitrator, hence the confusion.
