Nurses know the results of violence because we have, with our own hands, helped to mend wounds, to save lives, to weave back together what has been broken. Where there is pain, you will always find healers. It is our calling. So it was with great horror this week that nurses watched the land and water protectors at Standing Rock — those who have peacefully resisted the Dakota Access pipeline project — be attacked by a militarized force of police and armed guards.
