I sway to neither vote, too. It depends on what kind of crime wee're talking about. If it was government related than no one would ever have to know someone did it, and therefore that person would never have committed a "crime" because, depending on what one did, no one would be affected. If it were religion related -- depending on what religion wee're talking about here -- than it could very well affect someone, and will be known.
Like most philosophy, this can never be truly be answered. Wee can all take stabs though. ^^
