The Guardian: Investigators are having to learn new techniques to keep up with criminals that are increasingly using the internet for human trafficking.
Though official figures on human trafficking are notoriously hard to come by due to the crime's secretive nature, the International Labour Organisation estimates that 21 million people worldwide are forced into labour, including 4.5 million victims of forced sexual exploitation.
With the pressure of emerging technologies, anti-trafficking organisations, as well as law enforcement agencies, need to adapt their knowledge of new techniques and devices used by criminals. Smartphones are a new phenomenon; a couple of years ago the majority of crimes were being committed on desktop computers, Palmer said. "Now, nearly every crime seems to have some kind of phone involved in it."
