A girlfriend,wife, mother, brother , sister, coworker , etc may not turn the person in out of fear for their lives or lives of others. There could be a real fear of 'the what ifs'. 'What if I turn him in and they don't believe me? What if he finds out I turned him in? What if he hurts my kids, 'etc etc. The proof on this guy has to be very strong so no what ifs apply. And no fear that a mistake could be made that gets him off or out of jail. In my mind, there's a very fine line everyone involved is walking on. So far, no one has wobbled.
Let's hope someone's morals and hope for justice becomes stronger than their fear or doubt.
Let today be the day for Abby & Libby and their families.
