The National Security Agency is “deleting all call detail records (CDRs) acquired since 2015” to meet the requirements of the 2015 USA Freedom Act. This act ended the secret collection of call detail records, replacing the practice with a process in which the NSA requests specified records from the relevant companies. Because “it was infeasible to identify and isolate properly produced data” from the unauthorized data, the NSA decided to delete all records to rectify the inconsistencies. The deletions could create a Catch-22 situation for the agency, as a number of data privacy lawsuits may claim the deletions violate preservation of evidence orders.
