I do believe in doing an investigation although in some cases it will still come down to his word against hers. A lot of men who do this know exactly how to not be too overt or get caught. But plenty of times you can still get a sense of what really did happen in those cases by the way that people tell their sides. Is she geniunely rattled and distraught? Is he evasive or smug? I do believe in due process though.
