Bava Kamma 117: Comeuppance for R. Yochanan and the Resurrection of R. Kahana

Case reports and the rabbis' rulings: what happens when one Jew turns in another Jew to the authorities (specifically, objects). [Who's Who: Rav Kahana] A story: one who wants to show another's straw to the authorities, against better advice, and pays for that intent with his life. Which leads to a discussion of why the harsh response, including a window into the ways of the rabbinic academy. Plus, the drama between R. Yochanan and R. Kahana. Also, more cases of informants and thieves and the need (or not) to pay back. Plus, a new mishnah with an overflowing river.
