Operation Underground Railroad is an organization to stop child sex trafficking. You can get more information about them at their website: https://www.ourrescue.org. The organization is run by Tim Ballard, a former Homeland Security agent in the child crimes unit. He is now independent and has a team that goes undercover to buy children from sex traffickers so they can be set free. Members of the team call themselves abolitionists
They are financed by private donations and supported by law enforcement in the communities where they run sting operations. They get tips on where children are being sold and pose as buyers. Once the buy is completed, they call for law enforcement teams to come in and arrest the traffickers.
I first saw their story in Fox News Sunday with Chris Wallace. There are about two million children for sale on the black market. Hopefully Tim Ballard and his team can help cut into those numbers.
