I’ll try and answer what I think you’re saying Grim.
Even if #'1 & 2 are true, there’s additionally the unintentional bias that results from bad law.
We’ve noted certain laws that while on the surface are not biased, have the effect of targeting minorities or those living in poorer neighborhoods. This results in more arrests/convictions for minorities, minorities filling the prisons, people looking at the prison numbers and seeing the relative racial characteristics, which then get built into policies, leading to profiling, leading to a larger skew of the results, and the corresponding assumption on the part of many that certain ‘types’ of people are more likely to commit crimes (it’s easier to look at a large group of people and guess their racial background than socioeconomic, plus the DOJ figures give out data on race, not S/E).
I’m not saying that the DOJ stats are ‘valueless’, but that they shouldn’t be used as a predictor/basis for substantiating the need for racial profiling, or conclusions about racial characteristics of those who would most likely commit crimes.
Consider this:
The crime of drug possession is most often the result of a search done in an ancillary fashion to some other event (traffic stop etc.). IOW, in order to find the stuff, the cops already have to have a reason to search you.
At any given point in any given day, there’s likely to be more than 50% of the students at the local college campus in possession of some illegal substance (booze for the underage, drug paraphenalia, drugs, etc.). however, when the local narcotics squads are looking to bust folks, they don’t go to the campus, they’ll hang out at the inner city 7/11 type stores and look for people on foot, ask if they’re carrying, know some one who is, etc. ( One of my clients got asked while he was waiting for the bus. ) Gee, which place is more likely to have minorities? Who then, do you think then gets arrested/convicted?
I’ve worked in the system for 25 years. There were some ‘givens’:
If you were a minority and were charged w/a crime in certain areas of my state (roughly above a line mid mitten, plus a select number of counties in the lower part, for different reasons), the liklihood of you being sent to prison was pretty damn high. A white from those same areas, not so much. In a local rural county, police called to a domestic dispute, in the home where the whites lived, they left w/o arresting anyone, in the home where the minority woman lived, she left in handcuffs.
I talked to a local prosecutor recently, about a case where a minority guy was above that county line, and his response was “what was he thinkin’?”. That’s how pervasive it is.
So, when I hear folks talk about how minorities are more likely to be criminals, 'cause gosh darn, just look at the prisons, my first thought is “self fufilling prophecy works yet again”.
Yes, I believe that socio economic factors have an enormous effect, but not just the old adage about poor folk stealing more often (I"m not convinced that’s necessarily true - grew up in middle class America and I was one of the few of my contemporaries that didn’t shoplift at least a couple of times). But it’s not the only factor.
