Attorney-General Menahem Mazuz on Thursday rejected a request to investigate Balad MK Jamal Zahalka on suspicion of incitement against Defense Minister Ehud Barak.
Zahalka recently said in an interview on Channel One's Erev Hadash program that Barak "listens to classical music and kills children."
The complaint against him was filed by the Legal Forum for the Land of Israel.
Raz Nazri, Mazuz's senior aide, wrote to Legal Forum attorney Hila Cohen that Zahalka's words were "crude and improper both in their contents and style, and would have better been left unsaid."
Nevertheless, he continued, they were not a matter for criminal action.
"The best way to deal with this sort of expressions is in the public and ethical arena," Nazri wrote, and pointed out that they could complain to the Knesset Ethics Committee.
