> Why are they allowed to keep it I own land in the UK, which in reality means I brought it from someone who brought it from someone who brought it from someone who brought it from someone who was given it by the king as a reward for helping kill the previous owner. And if someone quarries marble on my land to make a statue, it has the same provenance. So we've basically decided there's a sliding scale. If it was stolen at gunpoint 1960 you've got to return it, but if it was in 1690 you get to keep it.
