Depends on how credible I found their claim, I suppose, and how serious I felt the crime was.
If one of you visited Canada and announced you had jaywalked (our word for walking across the street not at an intersection) I wouldn’t report you.
If Daniel visited Canada and announced he had interfered with a goat, I wouldn’t report him, although I would call him rude names.
If I honestly felt one of you had killed an innocent person, I would probably report you and I’d expect you all to report me in similar circumstances.
