Honestly, though? If someone offered me their child to buy, I'd give them whatever I had to get that kid away from them immediately--I wouldn't wait for the police, I'd take the kid and then call them. Obviously in this case she was selling her kid to fucking pedos (or they wanted him for some other nefarious reason) but I've seen stories like that before and thought, "I'd be in big trouble if I saw someone selling their kid, because I would buy it in a heartbeat to rescue it."
