The circus has been coming for years, I remember it in John Paul’s time. They usually do it around New Year’s/Epiphany. I rather doubt that it is a cover for child sex trafficking, usually performers are family groups.
Well, I understand. Perhaps the DM article is wrong, but they make it sound like it’s frequent. And on the matter of family circuses, that doesn’t mean much. If parents are pedophiles, they can be involved in trafficking their children or selling pornographic pictures of them. That’s sadly not unusual.
