Amazon has partnered with 400 law enforcement agencies across US for its Ring surveillance network

The scope of Amazon's partnership with police departments across the US continues to grow. In a new report, The Washington Post revealed that video-sharing programs between the Amazon-owned company, Ring -- purveyors of popular home security equipment -- number 400, which nearly doubles previous estimates. That figure, which the Post says was gleaned from Ring's company data, marks the first ever hard number on Ring's police partnerships which facilitate the exchange of user's home video footage with local law enforcement. A previous estimate from Vice using documents obtained through a Freedom of Information Act (FOIA) request put the number of partnerships at 200. Partnerships between Amazon and police departments are far more prolific than previously though according to a new report that details 400 collaborations across the U.S. Data obtained by the Post shows those partnerships mostly speckled across the across the Northeast, Midwest, and South East along the coast with many located in Florida, Texas, and Illinois.
