Use Of Technology In Kidnapping Case Highlights Privacy And Surveillance Concerns

The alleged kidnapping of a Boston woman last weekend has shed some light on just how ubiquitous surveillance is throughout the city.

Twenty-three-year-old Olivia Ambrose disappeared after leaving a bar Saturday. When her sister wasn't able to reach her, she used a smartphone feature that told her the last location of Ambrose's phone. Law enforcement then used that and surveillance footage, and found the Charlestown apartment where Ambrose was allegedly being held against her will. The man who lived in the apartment is charged with kidnapping.

While this story has a happy ending, it does highlight potential privacy concerns.
