To add to the great info already here, Flock is a private company. Think like Ring doorbells but for “Traffic Cameras”. They are mainly used to bypass laws and constitutional rights because its a for profit business. They have weaseled their way into entire cities. They not only provide back door access to any agency that pays, but they are actively building profiles on everyone they record. They know where you live, what you drive, when you work, where you work, how many people are in your family. They store all this without our consent or even notifying anyone.
Here’s a site that explains more and has an interactive map that shows where the cameras are located. deflock.org
