One large factor in this CRIME discussion is that many crimes are done by blacks, are NOT in proportion to the overall US Population. This point does not discuss the WHY of crime, as many who have posted are postulating upon. This data is by the FBI:
https://ucr.fbi.gov/crime-in-the-u.s/2019/crime-in-the-u.s.-2019/topic-pages/tables/table-43For example, the murder numbers are one example:
by white by blacks
3,650 4,078
percent by race
45.8 51.2
robbery show similar trends
percent, white vs black
44.7 52.7
one more, Aggravated assault
percent, white vs black
61.8 33.2
Anyone can go through the data to illustrate their point of view, but I think my examples are salient examples. Certainly murders get most of the attention in the media.
Note that blacks comprise about 13% of the US population, while whites comprise about 60% of the population. So blacks, comprising 13% of the population, commit (are arrested for, to be more correct) over 50% of the crimes in some categories, and about 30% of the crimes in many categories. If the blacks are committing most of the crimes, then it makes sense that many blacks are prosecuted (and thus convicted) for most of the crimes.
