Not the op, but how about this one:
The interaction of race, gender, and age in criminal sentencing: the punishment cost of being young, black, and male
"(1) young black males are sentenced more harshly than any other group, (2) race is most influential in the sentencing of younger rather than older males, (3) the influence of offender's age on sentencing is greater among males than females, and (4) the main effects of race, gender, and age are more modest compared to the very large differences in sentencing outcomes across certain age-race-gender combinations."
Translation: Young Black Males are the most screwed if they end up in court, likely to receive far longer sentences for the exact same crime. The severity of their likely sentence drops if they're female or a different race, or are older. "Young Black Male" is statistically treated significantly worse than "Young White Male", but once they start passing into middle age the significance drops.
A review of other articles (scholar.google.com) shows that sex&age are probably bigger factors though. An old black guy is about as well/badly off as an old white guy in most criminal trials. I hate Taylor Francis, btw, they don't take my university credentials to see the full papers, so I'm mostly working off of abstracts. Some of the issue seems to be that states with high percentages of poor black populations also tend to be the harshest sentence-wise. So a crime in a predominantly white state where the defendant(90% likely to be white) might get a year regardless of their skin color, but 'down south' where the defendant is statistically black(let's go with 60%), odds are he'll get a decade, again, regardless of skin color. Appropriate sentence for a crime is up to debate, of course, but I'm trying to keep it about race.
