DAF DISCUSSIONS - BAVA METZIA 2

Michael asked:

Why does the Mishna and Gemara spend so much time on when two people find a tallit on how and whether or not to make Shavua and not on trying to find an owner?

Michael, Highland Park, USA

The Kollel replies:

The ROSH (1:1) writes that the Mishnah is discussing a Talis that is found in a city which is mostly populated by Nochrim, for which there is no Mitzvah of Hashavas Aveidah, see Daf 24b. See also PORAS YOSEF.
