Who spoke that line?

At the very end of the orphanage scene, where the exhausted and bruised Joe lies on the ground and Jill says sobbing, "My poor Joe!" a male voice--the speaker is not clearly seen--says, "It's OK, kid--there's nobody in the world gonna shoot Joe now!"
I couldn't tell from the voice whether it was O'Hara; there was no Oklahoma twang in it so it couldn't be Gregg--could it actually have been a policeman who said that??
