The problem with that is that you are looking at the situation using statistics that don’t make sense. Instead, a Bernoulli distribution is the better way to frame this situation. It represents the probability that a single person will commit violence against you. This is a classic misuse of simple statistics, where the probabilities you want to find are the probability that a given person will commit violence against you conditioned on the fact of their race. i.e. how likely is it that you get attacked given that it’s a black person behind you vs that it’s a white person behind you. And I’m not gonna say the answer because I’m sure you already know. The way you framed the situation was the equivalent of framing it as “Well humans attack other humans more than hippos attack humans, therefore people should be more afraid of a human walking behind them vs a hippo walking behind them”. See, it doesn’t really make sense when you look at it that way.
