It wouldn't - except, as shown above, people are really hoping a slick lawyer could change that.
However, what people continuously fail to mention is one simple fact - The scientists WERE allowed to stufdy the remains after they were found, and EVERY conclusion was of someone who was NOT Caucasian and not a MODERN American Indian - they were of Asian ancestry. Period. End of story.
However, because some stupid clay modelling done that made Kennewick Man look like Patrick Stewart, some people decided it must have been a white guy who was killed by newly-arriving indians blah blah blah...
People can be ignorant about some things, is the bottm line.
It's completely irrelevant to our government's relationship with American Indians. It annoys me to see people advancing the notion that we should go back on our part of an agreement based on some junk like this.
