"The situation was created by people long dead. I don't think it's fair to hold people accountable for the actions of their grandparents."
We should be paying out reparations for slavery. You are oversimplifying things - emancipation and the eventual death of slaveowners did not cancel out slavery. You and I were born with an unfair advantage in this country because our ancestors weren't slaves and our ancestors never had to worry about getting lynched for looking at the wrong person. When the slaves were "freed," they had to deal with a hundred years of Jim Crow, and when they either fled Jim Crow or it legally ended, they had to deal with housing segregation and the income gap that was perpetuated by the last 500 years of injustice, and that still goes on today. White people in the USA don't have that on their shoulders at birth. Those dead people are still having a huge effect on this country, so why should we simply forget what they did?
"Right after the verdict was announced, shit went crazy in Ferguson, and it was most definitely not because there was a police presence, since the state troopers had been there for weeks"
You started watching a month or two late I guess. The police militarized days after the death of Mike Brown. They tear gassed media who were reporting from the designated media areas within a week of his death because there was too much press for their liking. The non-indictment (not verdict - there will never be a verdict) came much later.
"Just that the all-black neighborhood is more crime-filled than the "normal" (follows the general breakdown) neighborhood."
The black neighborhoods are impoverished, have fewer options for educating themselves, and have high rates of households headed by single parents. The income gap is roughly the same as it was in 1970. White families are roughly 20 times as wealthy than black families. Patrick Sharkey noted in his study of black and white youth between 1955 and 1970 that 4% of white kids grew up in poor neighborhoods while 62% of black kids grew up in poor neighborhoods, and the same study a generation later showed minimal change. He also showed that a black family living on a $100,000/year income lived in the same neighborhoods as white people did making $30,000/year. Thus, we're sustaining poverty.
How? I already wrote on that. Higher unemployment rates, poor-man's education, high incarceration rates, and a stunningly high amount of white flight to places like Lake Forest where they are sheltered from the problems of the real world with their green paper bubble.
You are clearly aware that poverty and crime are closely correlated. That's indisputable.
There is a degree of truth to what you say. The circular reasoning that says that because crime rates in black neighborhoods are higher, there are more interactions between police and black residents, and as a result, the stunningly high degree of brutal police action against blacks is not a race issue; rather, there are simply more opportunities because black crime is higher. It's a circle, and it's not wrong.
This view omits facts, though. We are seeing an epidemic of young unarmed blacks killed by police today, and the numbers in the past few years are comparable to the numbers of blacks lynched in the 1920s. Not only that, though - this "epidemic" is not taking place when black crime is high, but when it is low. As such, again, you aren't wrong - the issues in Chicago are somewhat unrelated to police brutality. However, the number of murders in Chicago in 2013 was the lowest since 1965. Why, then, is black-on-black murder, as it's been called here, so prominent and consistent? Because sustaining poverty sustains crime, and sustained crime increases instances of brutality - patience dwindles but crime does not.
Thinking about it this way. What you say is true - many problems that affect black neighborhoods and predominantly non-white communities grow out of the conditions in those communities. That's not the end of the discussion, though. It's just the beginning. The next piece is to realize that these conditions stem from slavery and Jim Crow because those caused housing segregation and the income gap, both of which still survive today and need to be addressed.
