Update: According to many tweeps including Ahmed Al Omran, the Saudi Commission denied these were its members. Also this photo has been taken in Riyadh (you can see an iconic Riyadh tower in the background of the upper photo). Ahmed says it may be from the Ramadan افطار صائم outreach.
Friends from Saudi sent me an email apparently showing members of the Saudi Committee for the Promotion of Virtue and the Prevention of Vice forming road blocks in Jeddah. The email reads (half jokingly): "Make sure you have your marriage cards (for couples) and remember the name of your maid and how many lightbulbs are in your bedroom". ht TAM
