According to the Thomson Reuters Foundation, tens of thousands of former slaves have been denied adequate compensation due to police not understanding the nuances of the laws regarding slave labor. In a more recent case where over 90 workers were freed, police were unaware that all enslaved individuals are entitled to compensation- not just bonded laborers. Currently, bonded labor is the most common form of slavery in India with around 18 million individuals forced to work in rice mills, brothels, and fields.
