Study Guide Bava Kamma 26 The Gemara suggests a number of kal v'chomer arguments to reach conclusions opposite of what is known to be the case, such as, one should be obligated for shen and regel damages in the public domain as can be derived from keren in the public domain. Each suggestion is rejected based on inferences from the verses in the Torah. Is there a ransom payment only by keren damages or would one also pay a ransom payment if an animal killed a person by trampling them on the property of the one who was killed? From a braita, they derived that Rabbi Tarfon holds that there can be a ransom payment for one who kills by trampling. The Mishna discusses the responsibility of a person for damages. A person is always responsible, even if it was an accident or someone damaged while sleeping. Raba brings a list of cases where an act was done unintentionally and discusses the law for different areas of law - damages, melacha on Shabbat, going to a refuge city for killing unintentionally, and damage to a Caananite slave on account of which a slave may go free.
