I don't know. I am quoting a TV analyst, don't remember who, from memory. The point that was made, whatever the precise text of the card, is technically a valid one, that a devout Muslim would be reluctant to identify himself with God even obliquely. Indeed, the killer was not an especially devout Muslim, nor were the 9/11 terrorists (some of whom visited nightclubs), nor were the Chechen terrorists (some of whom were gassed, then shot, nursing a bottle of Cognac).
The supposed non-musulmanity of the sniper was a canard injected by the media deliberately, and so was the notion that the sniper must be white. The notion that the police might stop nonwhite drivers or look for Nation of Islam members scared them more than the snipings.
