Perhaps I'm in the minority. But I can speak from my own personal experience, because my daughter WAS kidnapped & almost murdered 3 1/2 years ago.
I have no doubt in my mind that if the police had not found her - I WOULD have set out on foot searching for her, because up until the time I was informed that she had been found alive, I was ready & waiting to head out - as were other family members.
I fully understand why family members don't go out & search, and I understand why LE doesn't want family members to search. I know it's not always possible, or advisable, or even allowed (for the sake of preserving possible evidence).
All I know is this: when my beloved daughter was in danger, there was nothing & no one in Heaven or Hell or on Earth that could have kept me from searching for her if the police had not found her that night. This is not a hypothetical situation for me. It was real, and it was a nightmare. I will be forever grateful to the LE officers who set out that night in search of her. I will be forever grateful that LE found her alive. My daughter's abductor was convicted and is currently serving his sentence.
My heart goes to each & every parent who has faced or who is now facing this horrendous circumstance.
I commend CD for doing all he has done & continues to do for his little girl. I feel a kindred spirit with him, and if I could - I'd be right there searching with him.
