Previous Arab riots, intifadas and suicide bombings succeeded only when Israeli security was unprepared and ill-equipped to deal with the violence.
Ignoring violence only incites rioters, who are excited by the smell of fear, to escalate viciousness to brutality and murder.
Arabs in some areas of eastern Jerusalem have ambushed Jewish motorist for the past three years, and the police have responded after the fact.
There is virtually no constant presence of Israeli police in the Arab neighborhoods, exactly like Hamas-Bedouin areas in the Negev where police don’t dare to enter for fear of being overpowered.
It was only a matter of time before Israel had to make a decision: De facto recognition of Arab neighborhoods as Judenrein or lethal violence that is going to exact a heavy price on both sides.
Below is a video posted on Facebook of an ambush in eastern Jerusalem. The driver barely escapes massive rock-throwing and attacks on his car by driving on the sidewalk to maneuver around a barricade that had been set up as a death trap.
