The fatal police shooting of a Navajo woman in Winslow, Arizona is raising questions again about interactions with police. Officials say she threatened the officer with scissors when stopped during a shoplifting investigation. Loreal Tsingine’s family and friends are left wondering what kind of threat the 27 year old woman posed that warranted her death. Tribal leaders and others want an official inquiry to hold the police accountable for what many members of the public see as an overreaction. How are police trained to react in such situations?
