Why wouldn't they be "diverse" (as in different) if they were white SAs? Though every picture and video seems to imply there's probably few to zero white firefighters that came over. But that might just be selective photography. (To be fair the pictures don't seem to show any women either, but the official number is around 60, or slightly greater than 20%.)
