Roaring Lions and Goring Oxen

Kimby wandered the streets of Ladispoli, Italy, in early November. It was evening, and few people were around. Kimby didn’t get into any trouble. It was a good thing too, since Kimby was an escaped circus lion. Residents who found out about the escaped lion roaming their residential streets were obviously nervous. Yet, Rony Vassallo, who is responsible for the animals in the Rony Roller Circus, claimed the residents were in no danger. After all, the lion was born and raised in captivity and was domesticated. On the other hand, Alessandro Grando, the mayor of Ladispoli, near Rome, told residents to stay at home on Saturday while police and circus staff sought to catch the animal.
There seems to be a dispute between Rony and Alessandro about whether or not the lion posed any danger. Interestingly enough, this very subject was discussed recently in the daf (Bava Kama 15b). Rony holds like Rebbe Eliezer that even predatory carnivores can be domesticated. The Tana Kama says that these wild animals cannot be trained enough to put them in the category of domesticated animals.
