A child pornography case involving a California doctor has revealed that Best Buy's Geek Squad technicians allegedly worked with the FBI to uncover data on customer's computers for years, CBS Pittsburgh reports. A non-profit organization claims that the nature of the FBI's relationship with the technicians may have violated the U.S. Constitution.

The Electronic Frontier Foundation (EFF) filed a Freedom of Information Act (FOIA) lawsuit last year after it learned that the FBI allegedly paid Geek Squad employees to pass along information about illegal materials on devices sent in by customers for repairs.

One search led to felony child porn charges against Dr. Mark Rettenmaier after a technician reportedly went through the oncologist's deleted files and called the FBI in 2011. In 2017, a judge ruled that the images found in Rettenmaier's computer could not be considered child porn and the invasive search was illegal. All of the charges were dropped and the case was dismissed after a judge said an FBI agent made "false and misleading statements" to obtain a search warrant for the doctor's house.

EFF says their FOIA request revealed that Best Buy has been working with the FBI for at least 10 years. An FBI memo acquired in the lawsuit shows that Best Buy hosted a meeting and tour of their Kentucky repair facility for the FBI's Cyber Working Group in 2008. The memo and related email also claim that agents "maintained close liaison with the Geek Squad's management in an effort to glean case initiations and to support the division's Computer Intrusion and Cyber Crime programs."

Other court records uncovered in the FOIA search found that Geek Squad technicians were paid between $500 and $1,000 to actively search a client's computer.

The reports have raised concerns that the FBI is using the Geek Squad to bypass the Fourth Amendment, which prohibits unreasonable searches and seizures.

Best Buy spokesperson Jeff Shelman denied the claims in 2017. Shelman said their technicians don't do "anything other than what is necessary to solve the customer's problem," according to The Washington Post. Shelman added that if illegal material is found during those repairs, Geek Squad employees are obligated to contact law enforcement.
