In the weeks leading up to Super Bowl 50 last month, law enforcement officials found 42 potential human trafficking victims through a series of stings. At least two were under the age of 18, according to CBS San Francisco news affiliate 5KPIX. Human trafficking is a fast-growing global issue with a reach that impacts every state in the country. In 2012, the United Nation’s International Labour Organization, or ILO, estimated that there are 21 million victims of human trafficking all across the world, forced into labor or commercial sex work. Experts suggest it is the second largest criminal enterprise in the world—just behind the international drug trade—netting an estimated $150 billion each year, according to the ILO.
