Only 31 Arabs are arrested out of the hundreds of rioters who hurled rocks at police in East Jerusalem.
Most of the Arabs wore masks, which will make it difficult to identify them in court.
A crowd of criminals who defy law-enforcement officers and purposely evade identification is an enemy formation, but the police shrunk from shooting at the crowd, possibly out of fear of prosecution. Arabs know that rioters usually go unpunished, so they engage in riots as national sport.
The riots are instigated by the Islamic Movement, an official organization which the Israeli government refuses to ban despite decades of incitement.
Those who think that the Arabs would be satisfied with East Jerusalem might learn from the fact that the current round of riots was caused by the renovation of the famous Hurva synagogue in the Jewish Quarter of Jerusalem.
