While US justice certainly can be capricious and arbitrary, it is not entirely a random lottery whose eye it falls upon. And while those who believe in the centrality of personal responsibility and try to tell you that anyone who comes into contact with the police must have done something to deserve it are clearly deluded, there are things you can do in your life, or elements of your personal background and lifestyle that, though you never really opted into them, you may benefit from (one might call them 'privileges'), which will reduce the chances that you personally will run into trouble with the law quite considerably.

Your own personal odds are rarely the same as the average odds across the whole population. For anything. That's why insurance companies can exist.
