Nice assumption...(oh my heartstrings!). Actually, the genicide was committed by the Native Americans in 400AD, not to mention, more of their same guilt previous to that, perpetrating slavery being their long tradition and goal for 900-1000 years. We are talking millions of people, and the Smithsonian has plenty to hide on that matter. Previous employees share the government’s manipulation of artifacts on that matter. However, slavery was our sin, too, and had to be overcome.
