Why did they let it happen?

Just watching a ChildFund infomercial. They follow a little girl, who the viewer should sponsor, who wanted a blanket to keep her warm at night and a bicycle so her grandfather could take her to the clinic when she is sick.

I understand that it is an overwhelming problem and feel sorrow for the children, their families and the communities. My cynical response to the program is that little Lucia died from dehydration caused by diarrhoea after appearing in the infomercial. She was exploited and should really have received sponsorship for appearing in the ad. They exploited that little girl and then calmly state at the end of the infomercial that the viewer should help so that her death was not in vain.

Where is their responsibility?
