One of the things that scares me about the US criminal justice system is that it relies almost entirely on magical thinking and torture to secure convictions. I don't believe anyone is guilty unless they were literally photographed holding the bloody knife while standing over the body and even then I'll need some convincing to rule out potential mitigating circumstances.
Profiling is especially harmful. It's like the FBI knew that vast majority of serial killers where born in disfunctional families and neighbourhoods, but instead improving the material conditions of these families, especially with healthcare, they invented this bullshit pop culture version of serial killers, where the perpetrator is the master of deceit, literally the devil, and the profiler is the tortured soul that is trying to understnd the dark side of human psyche.
