U.S. anti-human trafficking Czar Luis CdeBaca talks with CNN about the role of governments and businesses in fighting slavery and also the historical context of slavery in the United States.
"One of our big problems with this under-reported crime is to not only find it, but then recognize it when we see it," CdeBaca says.
It's a problem with a long history in the United States.
"Since 1619 there's not been a day in the United States where someone was not enslaved," CdeBaca explains. "When the first Africans were brought off the ship from Angola, in the Jamestown settlement, it started a legacy that we have to continually fight in this country. Within a month of each other, both the United States and the UK abolished the slave trade in 1808. Unfortunately, in both countries, slavery continued for decades after that.
