Lyttons in a new book/Fake Reservations

Attached is an excerpt from a new book by Don Mitchell entitled “Wampum: How Indian Tribes, the Mafia, and an Inattentive Congress Invented Indian Gaming and Created a $28 Billion Gambling Empire.” The section about the Lyttons that is in this excerpt is called “Fake Reservations.”
 
A couple of things on the Lytton jump out from these excerpts. One is that that “The Lytton Band of Pomo Indians…appears to have been invented in order to open a bingo hall.”.  Another is section points out that in 1990, the Lytton’s had 20 members. Yet in 2005, they claimed to have 275.
