Saudi Arabia’s Day of Rage is this Friday.

"In the event that force is used, however, organisers expect the demonstrations quickly to turn violent: unlike in Egypt or Tunisia, in Saudi Arabia there's a large number of guns in private hands. 'In Saudi Arabia an estimated 80 to 90 per cent of families have a weapon in their house and around 50 per cent of those weapons are AK-47s,' an opposition source told me. 'If I go on a peaceful demonstration and I am shot by the police and I am the son of a tribe then 100 per cent definitely my brother will bring a Kalashnikov and kill the policeman who killed me and he will kill more, five or ten. They know this, the police, and so I've been told by many ordinary individuals and officers that no way will they shoot us even if they are given orders and if force is used it will backfire in a very aggressive manner.'"
