I say not black and white b/c as a parent I would have taken extra precautions. The cell phone being a notable one. Also, some written instructions to give to people (police, security etc) in case of emergency is just another that comes to mind. Perhaps they did these (or other things), I don't know, but it didn't sound like it.

Even so, you're right. It should be like 99% United, 1% parents.
