To your second point there has always been a contingent in the museum community who opposed the reparation of artifacts. This is not to say they may lament the means of acquisition but feel that the artifacts would be better protected in a more stable or better funded place. This group has been given more attention as of late. Especially with the rate of destruction currently occurring in parts of the middle east (re: ISIS). But even in other areas of the world this a concern. I've herd it said by some that artifacts returned to Peru cannot be fully accounted for. Admittedly, this was second hand, but it seems quite logical knowing a thing or two about the backlog of even the most funded museums.
