I looked at this thread before, but had not thought of a particular incident that forces me to say yes.

When fd first came to live with us we went to a horse show at a huge indoor exhibit center. She started losing it, so I tried to leave. By the time we got out of the door she was screaming and crying, "I want my mommy, your not my mommy, I wanna go home". She was physically fighting me with a strength that (at that time) blew me away. Of course we were at the back of the parking lot, and it took a good 45 minutes to get from inside the building to our van, with a total physical war, and her screaming the whole way. We had to force her into the van and I literally had to sit on her to drive home. Not one person intervened. No one questioned us, no one called the police. If I had been a witness, I would have. It could very easily have been a huge dramatic abduction, and not one person (and there were many who even stopped to stare) found it important enought to do anything!!
