From what transpired in the news, it would appear that Yishai is simply incompetent. It has nothing to do with his affiliation to Shas. He says he is angry; and so he should be angry at himself and realize that some of his mistakes may have caused the death of some innocent people. His sectarian attitude toward all non-ultra-orthodox and non-Jews goes to show once more that you can take a Jew out of the ghetto but you cannot take the ghetto mentality out of the Jew. Yishai, why don't you resign?
