Six days after Arafat Jaradat was arrested by the Israeli army and the Shin Bet, he was dead. Between the date of his arrest - February 18 - and the day of his death - February 23 - his lawyer Kamil Sabbagh met with Arafat only once: in front of a military judge at the Shin Bet's Kishon interrogation facility.

Sabbagh reported that when he saw Jaradat, the man was terrified. Arafat told his lawyer that he was in acute pain from being beaten and forced to sit in stress positions with his hands bound behind his back.

When it announced his death, Israeli Prison Service claimed Arafat - who leaves a pregnant widow and two children - died from cardiac arrest. However, the subsequent autopsy found no blood clot in his heart. In fact, the autopsy concluded that Arafat, who turned 30 this year, was in fine cardiovascular health.

What the final autopsy did find, however, was that Jaradat had been pummelled by repeated blows to his chest and body and had sustained a total of six broken bones in his spine, arms and legs; his lips lacerated; his face badly bruised.

The ordeal that Arafat suffered before he died at the hands of Israel's Shin Bet is common to many Palestinians that pass through Israel's prisons. According to the prisoners' rights organisation Addameer, since 1967, a total of 72 Palestinians have been killed as a result of torture and 53 due to medical neglect. Less than a month before Jaradat was killed, Ashraf Abu Dhra died while in Israeli custody in a case that Addameer argues was a direct result of medical neglect.

The legal impunity of the Shin Bet, commonly referred to as the GSS, and its torture techniques has been well established. Between 2001 and 2011, 700 Palestinians lodged complaints with the State Attorney's Office but not a single one has been criminally investigated.

Writing in Adalah's 2012 publication, On Torture [PDF], Bana Shoughry-Badarne, an attorney and the Legal Director of the Public Committee Against Torture in Israel, wrote, "The GSS's impunity is absolute."

Israel's High Court has been extravagantly helpful in securing the Shin Bet with its imperviousness to accountability to international law, and thus enabling widespread and lethal torture.

In August of 2012, Israel's High Court rejected petitions submitted by Israeli human rights organisations Adalah, the Association for Civil Rights in Israel and PCATI to demand that Israeli attorney general, Yehuda Weinstein, carry out criminal investigations into each allegation of torture by the Shin Bet.

And in the first week of February, two weeks before Arafat was killed, the High Court of Justice threw out Adalah's petition that demanded the GSS videotape and audio record all of its interrogations in order to comply with requirements of the United Nations Convention Against Torture (CAT) to which Israel is a signatory.

In May 2009, UNCAT condemned [PDF] Israel for exempting the Shin Bet's interrogations from audio and video recording, noting that such oversight is an essential preventative measure to curtail torture. Yet despite this admonition, in 2012 the Knesset extended the exemption for another three years.

Rationalising its failure to comply with this most basic requirement of recording interrogations, the State maintains that it is in the interests of "national security" that its interrogation techniques not be made public.

Arafat was killed under torture. Torture is routine. But the following is not routine: upon the announcement of his death, thousands of Palestinians, already unified in solidarity with the arduous struggle waged by Palestinian hunger striking prisoners, responded in force. At least 3,000 prisoners refused their meals; thousands poured into the streets of Gaza and impassioned demonstrations erupted across the West Bank. While the State of Israel continues to deploy its deadly arsenal of weapons to repress Palestinians, the banality of the evil of this regime is, as it will always be, eclipsed by the mighty Palestinian will for self-determination.
