Haj Yehiya's crime was not calling for an Intifada.
The crime is attempted first-degree racist murder. He came to a riot armed with two large firecrackers, planning to use them as weapons.
He shot the first firecracker at police.
Later, a mob stopped a car, and when they identified the driver as a Jew, pelted the car with rocks until the windows were shattered.
Haj Yehiya climbed on top of the car and threw the fireworks into the car. The fireworks exploded setting the car on fire.
The driver was saved from incineration by a concerned citizen who braved the crowd.
Considering Zippy Livni's attitude to racist graffiti (what she called "price tag terrorism") and how she ordered police occupation of a school as collective punishment for a non-dangerous attack on police, Haj Yehiya should expect years of imprisonment.
