Like prosecuting murderers? That CSI don't come for free. There is a reason society makes un-economic promises to victims of crime and casualties of War. They are not too dis-dimilar when you think about it.
I don't see how these compare: prosecuting murderers is supposed to prevent them from murdering again and, more importantly, discourage other people from murder. What is the parallel effect of proper burial of war casualties?
The families of the victims in both cases. The notion that justice (& dignity) outweigh the bean-counting. It is sort of parallel to insurance in that regards. The victims of crime and war are a small minority, and the rest of society makes small sacrafices on their behalf. If you look at the average cost of a gallon of gas delivered into Afghanistan, it is 100x markup, two orders of magnitude beyond "reasonable".
