Securing and auditing access to the enormous amount of sensitive data that this project would collect is a monumental task. Data leaks are an all-too-common occurrence because securing data is inherently difficult. The activities of citizens in Baltimore will be of interest to any number of third parties, whether those activities are illegal or not. We should expect third parties will gain access to the data. What will they do with it?
This project was of dubious value and rightfully decried as a civil liberties red flag years ago. Nothing seems to have changed except the increased scope of the project. This project should be shut down before we start something we can’t take back.
