Apparently that's a crime of the same order as selling land to Jews. That the boy was killed by his own uncle adds a stomach-turning dose of tribalism to this atrocity:

Relatives of the 15-year-old Palestinian boy who was murdered by members of his family last week on suspicion of "collaboration" with Israel have called on the Palestinian Authority to impose the death penalty on the culprits. The boy, Raed Sawalha, from the village of Hijjah in the Kalkilya district, was brutally tortured before being hanged. His body was discovered on Wednesday in a warehouse belonging to his family. His father, Wael, had locked him inside the warehouse after villagers claimed that they had seen the boy "chatting" with a Border Police soldier. The father told police that he only sought to "discipline" his son and did not know that other members of the family, including his own brother, would assault him and kill him... [T]he uncle has confessed to the murder. He told police investigators that he "lost his temper" when some boys in the village told him that his nephew had waved to a Border Police soldier as he drove by... Adnan Damiri, spokesman for the PA security forces in the West Bank, said that a number of the victim's relatives have also been arrested on suspicion of aiding the main suspect.

This is clearly a society ready for a state, having developed a robust civic sphere that eschews violent mob rule. They also seem pretty close to coming to terms with the existence of Israel and Israelis, so we've all got that going for us too.
