La parola alla difesa

I have not seen an episode since the mid-60s (YIKES, how long is that?), but I remember many of them. In one, these father/son are assigned the defense of a young Nazi. The man was defacing a synagogue when he was interrupted by the rabbi, who accidentally fell and hit his head and died. The man was caught and charged with murder, since it was assumed that he had killed the rabbi. There turned out to be a witness who could clear the man. When the Defenders finally tracked him down, he told them the most horrific story of his arrest and transfer to a concentration camp - and for that reason he would not testify for "one of THEM." Their response was, "Do you want us to be like them, ignoring the truth?" And that was how the episode ended - would the witness testify or not? How childish modern TV "drama" seems in comparison...
