There was even a perfect opportunity for Ozpin to said it when Yang asked him why he lied about Lionheart's dead.

But instead we got "because he was a good person once". It wasn't said in the show, it was revealed in the Volume 5 DVD Commentary that Ozpin had Lionheart appointed as Haven Headmaster to improve Human-Faunus relations in MIstral.
