Bava Kamma 30 - Shabbat December 2, 19 Kislev

Study Guide Bava Kamma 30 If one spills water in public, the Mishna holds that person responsible for damages it incurs. Rav again limits this to damage to clothing, not to a person. If so, what does this Mishna add to the previous Mishna? What are the laws regarding one who conceals thorns or broken glass in their own wall? What if they conceal it in someone else's wall and the owner of the wall breaks it? If one wants to be pious, there is a debate about whether one should learn nezikin, avot or berakhot. If one lays out straw/hay in the public domain to create fertilizer, and it causes damage, one is liable for the damages and the rabbis penalized the one who put it out and declared it ownerless. However, there is a debate between tana kama and Rabban Shimon ben Gamliel and it is unclear what they disagree about. Can the Mishna be explained according to Rabbi Yehuda who seems to think that one can create fertilizer in the public domain? Does the fact that one is allowed to do something, remove the responsibility for damage it may cause? Rav and Zeiri disagree about whether the straw itself becomes ownerless or only the amount that it increased in value by turning into fertilizer. Is this a debate among tanaim as well? Is that the issue that the rabbis and Rabban Shimon ben Gamliel disagree about in our Mishna?
