Shabbat 106: Fly High, Free Bird

When a destructive act can actually constitute "melekhet machshevet," even though it's not constructive in the least. Also: Trapping, which can depend on the size of the place used to capture the animal. And a discussion about a free bird... that does not accept authority (!). Plus: Another animated discussion among Chazal. And: Deer! What happens if the deer you're trapping can't run away? Well, it depends why it can't run. And what about grasshoppers and hornets and so on?!
