It's OK, there should be some relatives around to make a restorative payment of camels or wives. Unless they're from a particularly powerful clan, in which case they may be able to avoid paying the Diya even if they can't swing the outcome of the case.
Personally I find it quite odd that so many self-proclaimed libertarians are so favourably disposed towards what is essentially a system for punishing the collective for the actions of the individual.
That kinda sounds like a problem.
