I have in my posession the video,
Harry Potter Witchcraft Repackaged - Making Evil look Innocent
Apparently the author used material from her research into real witch craft and black magic in the Harry Potter series. The video details where she did this. It also pointed out that the company marketing the book had on it's websites links that children could follow to real witches coverns.
The series promotes and teaches witchcraft including black magic concepts which modern day wiccans will not touch. This is done through the vehicle of a childrens story.
A number of parents in the states have objected to their children having this book read to them because of its connection to the occult.
The film is done by Jeremiah films and can be obtained in this country from
