You didn't say that cops aren't to blame but the culture of black people when you said:
Now consider this cultural movement growing and expanding. Over time what do you think should logically happen to their interactions with law enforcement? I think the hostilities would naturally increase.
Logically, naturally the cops aren't at fault.
I see cops as a symptom. You are using a generalization fallacy there. I never said anywhere that cops were justified in their actions. I am trying to think about what could lead to it. Not all cops have that problem. There are also places in the country where these things don't happen the same.
Yet again, read the damn article, think instead of trying to fixate on defending the status quo idea.
Contribute to the thought process rather than attacking. Add something that adds to the hypothesis either by disproving it, or by adding other factors to measure.
Instead of simply grabbing onto little miscellaneous pieces of the article and trying to attack.
