Return of spears

I see the historical importance of the spears returned from Britain …first ones we know of that went to the British museum’s collections…however I’m confused over the way it’s all been described as ‘stolen’ when maybe they were gifts? Or just found on the ground?
Let’s be careful about all the language that is intended to be devisive. I know this is may not be a popular opinion with some but the way I see it Was Aboriginal land, Now Australian land…We Are One.
