Even if horrible, I don't worry about things that may have occurred a dozen times in the last 20 years, that I have never actually seen, and never will see. I am 40 times more concerned about horrible things that occur thousands to millions of times each year in the USA and elsewhere in the world.
Unless they are locked up 24, are never in public, let alone attend school, there are no sex trafficked children in the USA unless they are willing participants. To be otherwise is not possible because if the child was in public and told someone, anyone at all, the police would, within a few minutes, be on the case like a like a chicken on a June bug. Even if a child says nothing, a sad child will attract attention and people will ask question and call the police if they believe a child is being harmed or in danger of being harmed. People call the police even if they see a father holding his child's hand in the park. That is how indoctrinated 95% of all people are in the USA.
