Yes there are people that take advantage of situations. You may very well have more insight into that video and the woman than I do. I just posted it because it was one of many who experienced similar encounters. Many became christian because of it.
I'm not sure who Susan Smith is. Is that the person in the video? Or some other example?
I prefer ministries that are backed financially by their own churches. In other words, a minister's call is to be on TV or radio and his congregation helps him raise the money to do so. That way the people that tune in to listen can just focus on the message.
It seems the video, book, CD sells became an easier way to raise money than to keep asking the congregation for help.
