For white Americans, the discovery of children's bodies in unmarked graves near Indian residential schools is awful - but not a surprise.
But again, for white Americans, this may be the first time they've heard of residential schools, even though Johnson says, "When any group of Indians is asked who had relatives taken, every single hand goes up."
As Tadd Johnson goes around the Minnesota, talking to state employees about tribal-state relations, he says the most common reaction he hears is anger: anger that no one told them about Minnesota history from a Native perspective. For some, even learning that there are still Indigenous people in Minnesota is a surprise.
As people are justifiably upset over the residential school issue and want to help, Tadd Johnson says there's a lot of action allies can take, and it starts with asking your local school board to include Native American history in the curriculum for all students.
