Border patrol was also collecting and sharing the DNA information of migrant children, according to the agency’s data. Initial estimates show that the sensitive genetic information of about 133,000 teens and children was being uploaded and stored in this federal criminal database in perpetuity. The new CBP documents specifically cover how many US citizens have had their genetic information collected at various ports of entry, including major airports. What the law does not allow border patrol agents to do, Glaberson asserts, is collect the DNA samples of US citizens simply because they have been detained. DNA data can reveal incredibly sensitive information, including a person’s genetic relations and information about those relatives – regardless of their citizenship status.
