The family of a Palestinian man with autism who was fatally shot by Israeli police said on Thursday that it took a month for authorities to confirm the existence of security-camera footage of the shooting, raising concerns that no one will be punished for killing their son.

The existence of the footage had been in question throughout an investigation that the family says has been painfully slow. Rights groups say Israel has a poor record of investigating and prosecuting police violence against Palestinians.

“The police say the investigation is ongoing. Though it is late, we hope that it will end by delivering justice,” said Khiri Hallaq, the man’s father.

His son, Eyad, was fatally shot on May 30 just inside Jerusalem’s Old City as he was making his daily walk to the special-needs school he attended.

At the time, police said they believed the 32-year-old was carrying a “suspicious object” and said they opened fire when he failed to heed calls to stop.

According to various accounts, two members of Israel's paramilitary border police force chased Hallaq into a nook and shot him as he cowered next to a garbage bin.

Hallaq’s teacher, who was with him, told an Israeli TV station that Hallaq, who had difficulties speaking, fell to the ground after being shot, then ran for cover next to the garbage container. She said she repeatedly cried out to police that he was “disabled” and tried in vain to stop the shooting. At least five bullet holes were seen in a wall of a small structure at the site.

At the time, the shooting drew comparisons to the death of George Floyd in the U.S. and prompted a series of small demonstrations against police violence. The uproar crossed Israeli-Palestinian lines and drew Jewish protesters as well.

Israel’s defense minister, Benny Gantz, said Israel was “very sorry," while Prime Minister Benjamin Netanyahu called the incident a “tragedy” and promised a thorough investigation.

Since then, however, the family has heard little while the two officers involved in the shooting have reportedly been released from house arrest.

On Wednesday, after a month of pressure by the family, Israeli officials confirmed in a court hearing that investigators are studying security-camera footage of the shooting, said the family's lawyer.

Israel’s Haaretz daily had reported earlier this week that there may not be any footage, even though the streets and alleyways of the volatile Old City are lined with hundreds of security cameras.

The lawyer, Jad Qadamani, said the family has not been permitted to see any of the videos because they are evidence in an ongoing investigation.

Nonetheless, he said they are “more calm because we know the videos are there.” He called the footage “an important tool” in the investigation.

Qadamani said the family was frustrated that it had required so much effort for authorities to acknowledge the existence of the videos and that the investigation has dragged on for so long.

“Maybe there is a need to investigate, but not to this extent,” he said.

Cases involving police violence are referred to an independent internal investigations department under the Justice Ministry called “machash.” The ministry said the case remains under investigation and declined further comment. Israeli police referred questions to the ministry.

According to the Association for Civil Rights in Israel, cases referred to the department rarely end with disciplinary action.

It said that over 80% of more than 5,400 cases sent to machash from 2015 to 2018 were not investigated at all, and no more than 3% of complaints resulted in indictments. About 20 cases each year result in disciplinary proceedings for the use of force, and most of those end up with little more than a reprimand or reduction in rank.

It said the figures were based on official data obtained through a freedom of information request.

The statistics "speak for themselves,” ACRI said. “With an overwhelming majority of complaints against police violence never investigated and a complete lack of accountability on behalf of authorities, the cycle of the abhorrent use of police force will never cease.”

It said the police profiling of minorities is also a “severe problem.”

Qadamani, the family lawyer, said it has been difficult for them to trust the system but they remained hopeful.

“The feeling is very problematic. I expect and very much want to believe that they will take the real and correct steps for justice for Eyad,” he said.
