The Shepherd Security Series:
They took the oath to support and defend the constitution against all enemies, foreign and domestic, to protect the innocent, and to help those in trouble. Sometimes it’s not clear, though, is the person in their custody a witness or the perpetrator, a friendly or foe, innocent or guilty as sin? That's when it gets tricky.
