The Facial Recognition Technology Warrant Act, introduced by Sen. Chris Coons (D-Del.) would be the first federal restriction on law enforcement’s use of the technology, reports Sara Merken for Bloomberg Law.

“The bill…would require a court order based on probable cause before law enforcement could use facial recognition tools to conduct persistent tracking of a person for more than 72 hours, whether in real time or through historical records.”

“The bill also would require federal law enforcement agencies to work with the National Institute of Standards and Technology to create testing procedures that would “ensure the technology is accurate and does not have disparate error rates depending on a person’s gender, age, or ethnicity.”
