We were discussing true crime, real-world events, and the kinds of things that influence thriller writers when Joe asked me what I thought about Flock license plate-reading cameras. Flock cameras are automatic license plate readers, commonly called ALPRs. However, some traffic corridors in Broward County are stacked with Flock readers at nearly every major intersection. Cohen told me he has been getting a lot of questions about Flock cameras. If Flock cameras help police catch the people who burglarized a neighbor’s home, that matters.
