Which would be nice, wouldn't it. However reality is something quite different.
Why do you have different crime rates in different states?
Let's try and see if there's a pattern here. I'm going to put the position the state holds in terms of percentage of black population, the name of the state, then the position it holds in terms of homicide rate.
1) Mississippi 2nd
2) Louisiana 1st
3) Georgia 10th
4) Maryland 5th
5) South Carolina 4th
6) Alabama 9th
7) North Carolina 16th
8) Delaware 7th
9) Virginia 24th
10) Tennessee 11th
So, you can see that a high black population state generally has a higher murder rate.The problem is that Virginia in 9th has a murder rate at about the average. Why is this? Why is Georgia with the 3rd largest black population 10th in murder rates, but Delaware in 8th, with a 10% lower black population higher in murder rates?
The thing here that strikes me more than the high murder rates, is the fact that most of these states are in slavery country, segregation country, in the places where black people have been treated badly and will be treated badly.
Mississippi is 3rd in the number of people locked up, and spends $12,700 per inmate per year
Louisiana is 1st and spends $12,900
Georgia is 5th and spends $19,800
Maryland is 33rd and spends $26,300
South Carolina is 19th and spends $16,700
Alabama is 4th and spends $8,100
Again, we have different rates, nothing that says "this is the problem here", Louisiana spends little, locks up a lot and has a high murder rate. Georgia spends even less, locks up quite a lot and has a much lower murder rate, nearly half that of Louisiana but a black population of only 1% lower.
Mississippi spends $8,200 on education spending per person.
Louisiana spends $10,700
Georgia spends $9,200
Maryland spends $14,000
South Carolina spends $9,700
Alabama spends $9,000
They all don't spend very much on education, but again, Georgia has lower spending and lower murder rates. Hmmm....
So what is going on then? Nothing suggests there is one thing here that works.
You can go through all the statistics you like and you find loose patterns, but nothing which suggests this change. You need tons of statistics in order to get closer to the truth.
But then again, those whiter states which didn't have slavery, which spend more on education, are the states with lower murder rates. Is it because they're white, is it because they don't have people with a chip on their shoulder about slavery and segregation and have seen discrimination in their life time on a large scale, is it because the invest in their people? What is it?
