I don't believe so, for two reasons. One, there are all sorts of police officers with body cameras. In fact, when we see incidents that we're all very concerned about, often it's because a body camera captures it. Two, it's important to understand the depth of systemic racism.
Again, I don't want to say that all police officers are bad. A lot of the decisions that get made are.... It's just part of the system. We don't even understand or acknowledge the biases that we have. You could put a body camera on someone, but if you haven't actually addressed the systemic cause, all you're going to do is record the interaction. That may be good afterwards for someone like me who has to deal with it, but it's not actually very practical for the person who has to go through the experience.
