I have, and that's why I think there should be an open honest conversation about race and the potential differences via genetics/IQ. Black people on average have a lower IQ than whites, which isn't affected by education, and not taking that lightly as the whole matter of IQ is controversial in the first place. But there are a lot of interesting crime statistics that demostrate a strong possibility of black people being more violent as a whole than other races. The socioeconomic studies I've read show unemployment & poverty simply do not correlate to an increase in crime, but race does. http://m.imgur.com/MYeLVhv?r The problem is, trying to have an open and honest dialogue about these things makes white guilters and the black community cry racist, when it could be helpful to fixing the very issues that plague them. Such a broken households. Say more research is done and it turns out due to higher testosterone, lower IQ, or maybe a somewhat different pre frontal cortex is the cause of the apparent propensity of blacks for crime. We could help them have happier healthier lives. I know it's appalling to hear such things, but most species on earth have slight variations among themselves with lesser or greater capabilities per task, why is it so offensive that humans may not be any different? I'm not saying treat black people's a subclass of humans, but they could get better learning institutions suited to their capabilities to promote them having every bit of equal opportunity as everyone else does. There are a myriad of problems in the black community, some such as broken households, are self perpetuating but everyone is too fearful to address them. Edit since you asked for additional data but muted me? I guess here you go? This is the only one I have on hand on my phone; but here's the FBI crime stats for 2013. https://www.fbi.gov/about-us/cjis/ucr/crime-in-the-u.s/2013/crime-in-the-u.s.-2013/tables/table-43#disablemobile Here's the census of 2010 and 2014: http://www.census.gov/quickfacts/table/PST045215/00 Here is a well written albeit offensive blog discussing it in great detail. https://notpoliticallycorrect.me/2016/06/04/blacks-are-less-violent-than-whites/
