A Chipotle exec just got busted for cocaine possession. Guess what the charge was, and guess what the proposed punishment is. Guess his skin color (or culture, if you prefer).
There are so many factors that arise in something like that. For example, the Chipotle executive has access to better lawyers whereas a young black man may only have duty counsel. The Chipotle executive can better speak for himself, knows not to answer police questions, can get character references, is likely under first offense. I'm not saying it's okay, but certainly there are so many factors at play here it would be impossible to distill it to just one and name it as the most prominent single factor.
