From what I gathered, their parents sell them for about $300. The children then work off the debt. The teens are lured by a promise of a job as a waitress in a cafe. Then when they arrive, they are forced into prostitution. If they resist, they are beaten. Apparently a huge number of their "clients" are American men who come to Cambodia for the sex tours.
They did stage a raid for the show. But they were only able to rescue about 10 girls. At the end of the show they mentioned that the U.S. government is now giving the human rights group, International Justice Mission, a $1 million grant to help battle sex trafficking. But they made no mention of where we can donate money to help as well. I'm not sure what the point was of drawing so much attention to this issue without actually telling us how we can help. I wonder if it's in bad taste or something to do a news show on a topic and then ask for donations to address the issue. They also did not discuss the problem of the girls being returned to their parents after being rescued. 40% of the children rescued are eventually returned to prostitution. So I'm wondering why the parents rights to their children are not terminated (for selling them) and the children aren't taken to another country where they stand a chance of being adopted by parents who aren't so poor that they have to sell them just to survive.
