Publishing mug shots

This article from Reason Magazine was excerpted in The Week. It made a big impression on me. It's seems a harmless guilty pleasure to look at the mug shots of our neighbors, as well as celebrities - which are now published on websites official and not. But the author of the article notes that this phenomenon completely violates the principle of "innocent until proven guilty." It's troubling that we assume if someone gets to the mug shot stage, there must be a "reason." Very thought-provoking.
