I'm still waiting for more details, so I don't have a strong opinion either way on the officer's guilt. That this happened is terrible, of course.
I do think it's important to understand the history of law enforcement and incarceration in the Black community in America when considering events like this, and the anger that comes with them. Up until the early 1970s, incarceration rates had been pretty stable for decades, however over the next 30+ years (trends are beginning to change) these rates exploded. This growth has been driven by the War on Drugs and stricter penalties (longer sentences) on crime in general. Even as violent and property crimes decreased, rates of prosecution and incarceration for lesser crimes increased. With rulings on Terry stops (stop and frisk, etc.), which have effectively legalized or even promoted racial profiling (whites who are stopped are much more likely to be found with contraband...), and the higher baseline crime rates, the increase in police presence, incarceration and their negative consequences (1 in 14 Black minors have a parent in prison; roughly 50% of parents in prison were their household's primary bread winner) are profound in the Black community. The gains made during the Civil Rights movement have largely been undone by these changes in law enforcement.
As such, it makes perfect sense that some African Americans would feel as though the police are their enemies. I imagine a pretty compelling argument could be made that the police do more harm than good in low-income Black communities.
Good post and I agree to some extent. However, there is a question that needs to be asked: How many of the black people that are in prison are there because they broke the law? It doesn't matter if you think the law is stupid, immoral, or flat out wrong; if you want to live in the USA, then you have to follow the rules. We typically have zero sympathy for other races that break the law and are incarcerated, so why do blacks get some sort of special attention?
Sometimes, it really is black and white: don't break the law, don't go to prison. Seriously.
