A group of Amazon shareholders wants to stop the company from selling its facial recognition technology to law enforcement agencies.

The shareholders, who are concerned the technology will infringe on people's civil rights, filed a letter on Thursday to stop the sale of the technology, called Rekognition. Organized by Open Mic, a nonprofit that encourages shareholder activism at tech companies, the letter calls for the prohibition of sales to law enforcement agencies until Amazon concludes "that the technology does not cause or contribute to actual or potential violations of civil and human rights."

The resolution calls for Amazon's board to consult with technology and civil liberties experts to determine how Rekognition could violate privacy or civil rights and how it could "disproportionately impact people of color, immigration, and activists."

According to a statement from Open Mic , Rekognition analyzes images and videos of faces, to identify and track people and their emotions.

However, in a test, Rekognition incorrectly identified 28 lawmakers as people who had been arrested, disproportionately misidentifying black and Latino Congress members as people in mugshots.

Michael Connor, executive director of Open Mic, said the sale of Rekognition presents a "considerable risk for the company and investors."

"It's a familiar pattern: a leading tech company marketing what is hailed as breakthrough technology without understanding or assessing the many real and potential harms of that product," Connor said. "Sales of Rekognition to government represent considerable risk for the company and investors. That's why it's imperative those sales be halted immediately."

According to the resolution, law enforcement in Florida and Oregon have already begun testing the technology.

The resolution included a quote from Brian Brackeen, former chief executive officer of Kairos, another facial recognition company, who said that companies that provide law enforcement with facial recognition software are "willfully endangering people's lives."
