From 1978 to 1986 Zamir served as the Israeli Attorney General. During this period, Zamir is remembered for his fight to investigate the GSS during the Kav 300 affair, after two terrorists caught alive were secretly murdered by GSS officer Ehud Yatom (brother of Danny Yatom). Zamir demanded from Moshe Arens, then Minister of Defense, to appoint a committee to investigate the accusations. On May 18, 1986 Zamir demanded to prosecute Avraham Shalom, head of the GSS. Prime Minister Shimon Peres refused and removed Zamir from office, replacing him with Joseph Harish.
