My mother is a true-crime buff, and a devout Jew. I'll admit that I've only known her since the time I was born, but somehow the idea that her learning PhotoReading without changing the nature of the materials she reads would turn her into a killer is... interesting. I could see her developing the perceptual frameworks of a detective or profiler. I believe that her skills at empathy both are enhanced by and naturally draw her to true crime books.
