According to the New York Times, disenrollment is a very real event, and could become a real problem. Tribes in California alone have disenrolled at least 2,500 members in the last decade. As quoted in the New York Times, David Wilkins, a Lumbee Indian and professor of American Indian studies at the University of Minnesota states, "Sometimes it is political vendettas or family feuds that have gotten out of hand, but in California, it seems more often than not that gaming revenue is the precipitating factor."
Recognize the beardless, tattoo-less biker wannabe? That's Richard Speight Jr. He has an extensive resume having performed in dozens of shows like Supernatural (Trickster/Loki), Band of Brothers (Sgt. Warren "Skip" Muck), Justified (Jed Berwind), Jericho (Bill) and bunches more.
Michael Spears, who plays Cheyenne biker and tough guy, Mika DullKnife, wasn't always so big and scary. He got his start in a little movie called Dances with Wolves at the age of 13 playing the character Otter. Spears is a member of the Sicangu Lakota Lower Brule Tribe and lived on the Lower Brule Sioux Reservation until he was in fifth grade.
This isn't the first time Richard Speight Jr. and Michael Spears have appeared in a series together. Both actors also played characters in the miniseries Into the West. Another actor in that miniseries was Jason Douglas, who you might remember as Mason Vaughn in the Longmire episode An Incredibly Beautiful Thing.
