In a letter dated Thursday, the lawmakers expressed concern that the Rekognition software wasn't yet accurate enough to be used by law enforcement.
"Facial recognition technology may one day serve as a useful tool for law enforcement officials working to protect the American public and keep us safe," the members of Congress wrote. "However, at this time, we have serious concerns that this type of product has significant accuracy issues, places disproportionate burdens on communities of color, and could stifle Americans' willingness to exercise their First Amendment rights in public."
The letter was written by US Reps. Jimmy Gomez, John Lewis, Luis Gutierrez, Jan Schakowsky, Pramila Jayapal, Ro Khanna and Judy Chu and Sen. Edward Markey. It follows two other letters written by members of Congress that requested an "immediate" meeting with Bezos after a test of Rekognition the lawmakers with mugshots of criminals.
In Thursday's letter, the lawmakers expressed concern that Amazon is "actively marketing this product to law enforcement entities, including US Immigration and Customs Enforcement." They cite reports that law enforcement officials are starting to use cameras to collect footage of bystanders and transfer the data to Amazon servers for facial recognition analysis.
The politicians also say Amazon has "failed to provide sufficient answers" to the questions raised in the earlier letters. They renewed their inquiries about how Amazon tests for facial recognition accuracy, whether the results have been independently verified and how the company tests for bias in the facial recognition results.
The members of Congress asked for answers by Dec. 13.
Amazon didn't immediately respond to a request for comment.
