Pattern of Errors

How killers get caught, and why some never are.

One case, one mechanism, under a minute. Adjudicated cases only, sources on screen and in the description, victims named with respect.

Each case opens on an exhibit: in color when it ended in an arrest or a confession, in gray when no one was ever caught.

Five series: The Catch, The Failure, The Myth, The Pyramid, The Class.
