Background: I am an only child, and my husband has two siblings. My dad has a younger brother who is homeless (we think), and has several warrants for his arrest and outstanding fines for everything from drugs, robbery, assault, etc.
DH and I were discussing that my dad felt that he would have to turn in his brother to the sheriff (in America) if he turned up. He has been missing/gone to another state/possibly dead for almost 10 years now, so it is basically just hypothetical.
My husband said "I would never turn in my own brother for anything." Maybe it's because I have no siblings, but even if it was a parent, aiding and abetting a fugitive, is a crime in America. It was shocking because my husband is a rule follower and has literally never lied.
WIBU to turn in a sibling you know is a criminal? Not just like paperwork or not paying taxes, but multiple crimes against people and property.
