If there were no racial barriers then they would burn San Francisco to the ground while singing Istanbul was Constantinople. They, of course, meaning the inquisitors. The racial barriers are what keep them employed. Without a job, they’d throw the party of the century, inquisition style. Of course their idea of a good time is burning a city. Are they crazy? Wouldn’t they have to be, to do what they do to the people they catch? They’ve never liked San Francisco because of all the work they have to do there. And as for Istanbul was Constantinople? Well that’s just a good song.
