From "Sisters in Law/Saudi women are beginning to know their rights," by Katherine Zoepf in The New Yorker.
The Saudi Gazette no longer displays the quoted article, and I couldn't find it through the Wayback Machine or Google Cache. This might be the relevant text, at Crossroads Arabia. It contains the quoted text — which I've boldfaced — and purports to be "a good piece in the Arabic daily Alsharq from the Eastern Province (here translated by Saudi Gazette)":
An electronic newspaper recently reported that a housemaid in the city of Al-Ras, Qassim province, had performed sorcery on her sponsor and his family, immobilizing their movements. It said the Commission for Promotion of Virtues and Prevention of Vice (Haia) team specializing in dispelling sorcery and talismans was able to discover and ward off the sorcery at the right time.Yes, you want to slap your head at the idea of how to prove something the nonexistence of which is obvious. But attention to the need for evidence is a first step out of the predicament for people who do believe in witches. In American history, questioning the use of "spectral evidence" — testimony by persons claiming to be afflicted by invisible forces — was central in ending persecution:
The team had safely dispelled the magic the same way the security forces would diffuse explosives. The housemaid, who was not identified, was handed over to the concerned authorities for investigations and legal action.
This means that the case has taken a legal course and will be considered by a court. This step raises a number of legal questions that should be posed to legal experts. As the woman may seek the help of lawyers to defend her at the court, these legal representatives should then know how to deal with cases involving magic to provide their clients with correct and sound legal advice.
The main question that arises here is: how will anyone be able to prove a sorcery issue? How can anyone prove that the claimant and his family were under a magic spell? Has humanity been able to invent a device to measure the level of magic in bodies? Will this device be used as criminal evidence in courts, similar to DNA tests and coronary reports?
On May 31, 1692, [Cotton] Mather wrote to one of the [Salem witch trial] judges, John Richards, a member of his congregation, expressing his support of the prosecutions, but cautioning; "do not lay more stress on pure spectral evidence than it will bear ... It is very certain that the Devils have sometimes represented the Shapes of persons not only innocent, but also very virtuous. Though I believe that the just God then ordinarily provides a way for the speedy vindication of the persons thus abused."... The later rejection of spectral evidence by Governor Phips and its exclusion from trial beginning in January 1693 immediately brought about far fewer convictions....
