This statement below, from the current thread article would seem to tie in with the cone of silence and outright censorship and games played with the Kennewick Man:
"When the DNA analysis came back, Stenger was in for a shock. The hair did not belong to a native American. Baker, who carried out the analysis, says: "It's possible that the so-called paleoindians are not the ancestors of native Americans. Either they didn't leave any ancestors, or they were replaced by other peoples."
The cover up on the Kennewick Man went right to the highest ones in control of America at that time.
Now for a few paragraphs from the Kennewick Man that you linked in your reply:
The lack of head flattening from cradle board use, minimal arthritis in weight-bearing bones, and the unusually light wear on his teeth distinguish the behavior and diet of Kennewick Man from that of more recent peoples in the region. A fragment of the fifth left metacarpal analyzed by AMS has an isotopically-corrected age of 8410 +/- 60 B.P. (UCR 3476) (ca 7300 to 7600 B.C.). Amino acids and stable isotopes indicate heavy dependence on anadromous fish. DNA was intact, but two partially-completed extractions were inconclusive.
The man lacks definitive characteristics of the classic mongoloid stock to which modern Native Americans belong. The skull is dolichocranic (cranial index 73.8) rather than brachycranic, the face narrow and prognathous rather than broad and flat. Cheek bones recede slightly and lack an inferior zygomatic projection; the lower rim of the orbit is even with the upper. Other features are a long, broad nose that projects markedly from the face and high, round orbits. The mandible is v-shaped,with a pronounced, deep chin. Many of these characteristics are definitive of modern-day caucasoid peoples, while others, such as the orbits are typical of neither race. Dental characteristics fit Turner's (1983) Sundadont pattern, indicating possible relationship to south Asian peoples.
Current Status of Kennewic Man: On August 30, four days after the startling radiocarbon result, the Corps insisted all studies be terminated and soon took possession of the skeleton. After publishing their intent to repatriate the remains to an alliance of five tribes and bands--Umatilla, Yakama, Nez Perce, Wanapum and Colville--the Corps received numerous requests for scientific study from citizens, congressmen and anthropologists. The Colville then filed a separate claim of their own. A group of internationally-known archaeologists and physical anthropologists filed suit, asserting that NAGPRA does not apply to this case and seeking the opportunity for study. The Asutru Folk Assembly, a traditional European religion, also sued for the right to determine if this individual was their ancestor. The Umatilla, who have taken the lead on the issue, intend immediate reburial in a secret location. The remains now lie in a federal repository awaiting resolution.
Doesn't all of this sound familiar? :
