... I believe in another thread you claimed to be scientific minded... Yet you're going about this in a very unscientific method.
None of the charts you posted actually show that black people are committing crimes at a rate 6 times higher than whites. What it shows is that they are incarcerated about 6 times as often. This COULD mean that they are simply committing more crimes. It could mean that black people are more likely to be arrested, and police look at them more closely (stop and frisk). It could also mean that they are incarcerated more often for the same or similar crimes (see the discrepancy in punishments vs crack vs cocaine). It could also mean that law enforcement is heavier in black neighborhoods, meaning that black people committing minor crimes are more likely to be caught than a white person committing the same crime in a white neighborhood. It could also mean that white people typically have access to better legal assistance and are less likely to be found guilty. Custody also presumably included people who are awaiting trial, so it could be that part of the discrepancy is due to white people being better able to afford bail.
You've also somehow concluded that racism is based on criminality, and somehow didn't consider it could be the other way around.
You are going from the first part of the scientific method (observation) and skipping right to the last part (conclusion). You're skipping the whole middle part where you hypothesize an explanation for that observation, and test to see if that hypothesis is correct. You went straight from "there are more black people in state custody" to "black people commit more crimes and that's why there is racism and police brutality". That's a really wild leap in logic that, perhaps not surprisingly, sees you coming to the same conclusion you had before looking up any of this data.
I did not skip the explanation, I'm rather looking for one... I agree that these are factors that play a role yes but is that enough to change the overall picture? One is arrested for committing a crime.
You conclude that black people 6x crime rate comes from the police keeping an eye on them for minor crimes, but you skipped the "Official FBI stats say that 49% of murders have been committed by African Americans in 2015" and the second graph that shows a huge difference about the most serious crime that is murder.
don't mind my username, that was more than 10 years ago, I'm a different person now, amazing how people change ^_^
