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.
White people with the same hair color are the bane of my existence. When I'm introduced to an old white guy at work, I always say "nice to see you" because I have literally no idea whether we have met before.
