Over 30 civil rights groups have raised serious concerns over Ring doorbell-security system’s police information sharing program. Amazon acquired Ring for $1 billion last year. Following the move, Ring partnered with over 400 police forces from across the country giving access to customer security footage, as reported by the Washington Post.

The civil rights groups are now fighting for homeowners’ privacy, which they believe Amazon has compromised. In their recent letter, the groups argue that Amazon has been incentivizing police “to promote their technology,” while feeding them with relevant “talking points.”

“With no oversight and accountability, Amazon’s technology creates a seamless and easily automated experience for police to request and access footage without a warrant, and then store it indefinitely,” the letter read.

“In the absence of clear civil liberties and rights-protective policies to govern the technologies and the use of their data, once collected, stored footage can be used by law enforcement to conduct facial recognition searches, target protesters exercising their First Amendment rights, teenagers for minor drug possession, or shared with other agencies like ICE or the FBI.”

Reports also indicate that Amazon employees, in both the U.S. and Ukraine, had uninhibited access to customers’ live video footage. Amazon started the branch in Ukraine in 2016.
