With a 50% plus unsolved rate for murder in the major cities, you can’t even work with good numbers to determine murder by ethnic group.
“With a 50% plus unsolved rate for murder in the major cities”
The major cities have solved murder rates of between 14% and about 20%. There are just too many murders and not enough resources. The 50% plus unsolved figure applies to the overall murder rate for the entire country. So, the unsolved murder rate in the major cities is 80% to 86%. BTW: The solved murder rate in my small rural county for the last 40 years is 100% AFAIK. Of course, I am aware of only 1 murder in that time.
