On 8 November 1995, a state commission of inquiry was established to investigate the circumstances surrounding the assassination of Prime Minister Yitzhak Rabin by Yigal Amir. It was chaired by the recently retired president of the Supreme Court justice Meir Shamgar. Its other members were Zvi Zamir (Mossad director, 1968-74) and Ariel Rosen-Zvi (professor of law at Tel Aviv University). It submitted its 332-page report on 28 March 1996, two days after Amir's conviction. Its main conclusions fell into two categories. Concerning the assassination itself, it concluded that the Shin Bet (Shabak)/General Security Service had no prior knowledge of Amir, though it was criticized for not taking seriously a general description of Amir and his intentions that it received some five months before the assassination. Otherwise, the intelligence units were generally exonerated. The Shamgar Commission totally rejected any suggestion of a broad-based conspiracy surrounding the Rabin assassination.
The second section of the report was highly critical of the special unit of the Shin Bet assigned to protect very important people (VIP), including and especially the prime minister. According to the Sham-gar Report, the "thinking and performance [of the VIP unit] were extremely flawed, and the management culture of government authorities . . . was weak." It declared that if Shin Bet director Karmi Gillon and the chief of the agency's protection unit had not already resigned, it would have recommended their dismissal. The commission did recommend the dismissal of the three next-highest-ranking Shin Bet officials in the protection unit, barring two others from command positions for specified periods of time, and lesser sanctions for officials of the next two echelons down. A 118-page classified appendix to the report recommended stronger intelligence liaison and cooperation between the police and the Shin Bet, more intensive surveillance of subversive Jewish organizations, and better control of undercover agents by the Shin Bet. On 31 March 1996, the government of Israel adopted the recommendations of the Shamgar Report.
