In a previous posting about Johnny Depp, I said there was no evidence he was adopted by the Comanche Nation rather than a Comanche family. I stand corrected. Here's the evidence:
The certificate says "Honorary Tribal Member." So now it's official: Depp is an unofficial member of the tribe.
He'll be an official member, and thus an Indian, when the Comanches strike the word "honorary" and give him full citizenship. Until then, he's still a white man with a small amount of Native blood.
