Oh, I actually really enjoyed seeing the Tree of Guns, mainly because I'd met a number of the artists who worked on it in Mozambique.  The guns-to-sculptures program there is really very impressive.  The sculptors work out of a studio/gallery/workshop in a converted old house on a side street, near downtown Maputo, and on weekend evenings all the young arists in town hang out, drink beer, listen to music.  It's great.  And they were just thrilled when the British Museum commissioned the Tree.

At any rate, that's not really an artifact, it's a commissioned work of art, and the people who made it were compensated as any artist would be.  I don't have such a problem with that.

But yes, the bitter irony of a Tree of Guns, with everything it symbolizes, being displayed alongside historical artifacts obtained through centuries of looting a continent at gunpoint....
