That is relatively recent and there is/was a long historical record of crime rate among whites, blacks, hispanics, asians.
Of course it is going to vary with which crime(murder, armed robbery, rape, etc), but generally hiapanic crime rates were double that of whites and black crime rates were quadruple that of whites. The exception to this is white collar crime such as embezzlement.
It is not just crime rates based on race. They also keep stats on sex and age.
In fact, age is a better indicator of crime than race. It doesn't make any diferrence whether you are black, brown white, yellow, or pink, most crime is committed by those that are 19-28 yoa. Those that are 29-38 commit less crime. Those that are 39-48 even less. 49-58 even less.
Also, the stats show that there are many, many more murders committed in conjunction with another crime(such as robbery, rape, etc) than there are murders committed as a stand alone crime.
Law enforcement doesn't keep stats on crime by class but sociologists do. Low class whites commit more crime/murder that middle class whites who commit less than upper class whites. The same is true for blacks, hispanics, and asians.
Yes, they fit the age group for high crime rates.
But when compared to other college graduates their age, I'll bet their crime rate is at least 5 times higher.
And that's just for arrests.
People don't get caught each time they break the law.
I'll bet the “lawless” rate for NFL players is 10 times higher than college grads in their age group.
