Bear in mind that it's not that long since various factions in Bosnia were chucking EACHOTHER in rivers, not to mention beating to death, shooting, poisoning wells, locking eachother in compounds to starve to death, etc, etc.
It's also not that long since, that it was perfectly acceptable in THIS country to drown litters of unwanted kittens or pups. If you've ever been to a place like rural Bosnia you'd realise that they have a different set of priorities to what we have, and even having said that, I'm not sure I've done justice to just how different our two cultures are.
