Some are skeptical of the authorities’ intentions, believing that they have deliberately let violence run amok in order to weaken the Arab minority in Israel, which largely identifies as Palestinian.
“It is all part of the Israeli-Palestinian conflict,” said Jamal Fattum, 47, a lawyer and social activist from the Arab town of Nahef, in northern Israel. “We are part of the Palestinian people, who have national aspirations.”
Mr. Fattum, who has helped organize protests against violence and government inaction, has at least 10 security cameras monitoring his upscale residence. But one night in April his family awoke to shooting at the house and a boom as their car went up in flames. A bullet pierced the thick, wooden front door and lodged high in his dining room wall.
Mr. Fattum said he had no idea who the masked assailants were or what they may have wanted, other than to silence him. The police have investigated but made no arrests.
But in many cases, victims refuse to cooperate.
Whether out of mistrust of the police, fear of revenge, or both, officials and experts say, witnesses and relatives of victims often stick to a code of silence. Some crime scenes are cleaned up before the police arrive.
