The perennial one is refusing to believe staff over students. Like a school counselor forced to resign for a student not graduating despite the fact that it was well-documented that the counselor had given the student a clear graduation plan and provided  multiple warnings about the consequences of failing to follow the plan.  Or the numerous cases of students assaulting teachers in front of multiple witnesses and the board members punishing the teacher because "that student would never do that."  Board members have also been known to get up at new teacher orientation and tell the teachers to hurry up and train their replacements so that the board can get rid of the new teachers.  

Am I saying that all elders who were forced to attend the boarding schools are like this, no.  However, there are enough of them that it is negatively affecting the tribes.  To move forward with minimal bias there must be healing, but healing must begin with sincere acknowledgement of past traumas.
