No, of course an adult man should not go off with an underage girl. Just saying, this girl probably was vulnerable due to a chaotic home life, and she was eager to go with him to escape the home.

At the time of the Amber Alert I said this was probably simply a family problem visited on the public.
I got attacked for it. Turns out I was right
