You're wrong on pretty much every count.
"It would make sense that the high criminality rates from African Americans must be the main source of racism, and police brutality to some extend." That's an explanation/conclusion right there. You've concluded that's the sensible reason that must be the case. If you'd like to revise that, that'd probably be smart, but that's not looking for an explanation, that's asserting one.
I on the other hand didn't conclude anything. "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." I did not say that this is a sensible proposition, or that it must be the case. I simply offered it as a possible explanation. "It could be."
As for the FBI statistic, you did not source that at all, and as far as I could tell, that's wrong. https://ucr.fbi.gov/crime-in-the-u.s/2015/crime-in-the-u.s.-2015/tables/expanded_homicide_data_table_3_murder_offenders_by_age_sex_and_race_2015.xls According to FBI data the actual number is 36.7. Even if we assume that every murder where the race is not listed was committed by a black person, this would leave the ratio of black to white at about 2:1, and this would not come close to explaining the proportions in the previous chart that you claimed "hold up".
Moreover, I don't see how this is at all relevant. There are over ten million arrests per year statista.com/statistics/191261/number-of-arrests-for-all-offenses-in-the-us-since-1990/. In 2015 there were 15,000 murders. Even if every murderer were apprehended by police, apprehension for murder makes up such a small amount of police interactions that I don't see where it fits in to this conversation.
Lastly, one is not arrested for committing a crime. One MIGHT be arrested for SUSPICION of committing a crime. That's a major difference.
Just for fun, I wondered why exactly you were posting charts from seemingly random years when data from more current years is readily available. A quick google image search explains why. These were the pictures that were posted on wikipedia.
Really, the quality of research being done here does not show an honest effort to understand a complex issue, but an attempt to do a cursory search to confirm a position that was already held.
Thanks for the links. These numbers confirm my initial quote of 49% reported by FBI for 2015, since it is 53% of murders committed by African Americans if you exclude the unknowns, the overall picture does not change. The sample is big enough anyway.
You are right for the homicide chart, it is victims instead of murders! It still helps us to find out who kills who. If half the murders are committed by African Americans and they are also the most victims by far, then it seems they kill each other a lot. Pretty ironic for the BLM movement... : /
Oh what a discovery, it's google and wikipedia yes, time optimization you know? I don't wanna waste ages to reach the same statistics. I never did a deep research/analysis on the matter, nor did I claim to. I suggested a possible explanation, and since I am not American I'm looking for other opinions in order to better understand what's going on and shape mine. That's why my first line on the thread was "any comments on this chart?".
And yes I had an impression of how black crime rates are higher, judging from trending music videos and the rappers that ended up in jail...
"You're wrong on pretty much every count." and you are always right O.K.
And if crime figures that relate police and black people do not relate to the conversation by you, then what does? If you have something that relates more then share it.
Of course there are many factors that relate to the numbers we have, which you already mentioned and I agree, but the overall picture is too obvious to be altered by those. When a 13% of the population does 50% of the murders and has an equal prison population with the 72%, it is clear that in US there is a big issue with crime from African Americans and police is obviously handling it very very badly.
I am adding previous figures posted for the sake of completion. Maybe someone has something else and can shine some light.
don't mind my username, that was more than 10 years ago, I'm a different person now, amazing how people change ^_^
