The Transaction Record Analysis Center, an obscure Arizona nonprofit’s database, is accessible by more than 600 federal, state and local U.S. law enforcement agencies without judicial oversight, The Wall Street Journal reports. TRAC was established in 2014 by an order from the Arizona state attorney general’s office to monitor international money transfers between the U.S. and more than 20 countries, as part of anti-drug trafficking settlement with Western Union. Data collected by TRAC includes full names of the sender and recipient and the transaction amount.
