Are you sure? Since most homicides are intra-racial [1] (despite the impression one gets from those the media choose to focus on), we can use victim race as proxy for offender race (I'd use offender race directly, but then you'd just blame it on police racism). Since it's hard to manufacture a corpse, or fake its race, we can further assume that data is largely free of police bias.

So white+Hispanic are 50% of homicide victims [2] (which we use as proxy for perpetrators), and 58% of the prison population [3]. For blacks, its 44% and 37%, respectively. Doesn't look particularly skewed to me. There is some anti-white+Hispanic bias, but since we're looking only at homicide to avoid police bias, we're not seeing the whole picture, which may explain the disparity.

Not necessarily. People "not being logical" might simply mean that their decisions are emotional. Emotions are not logical, but that does not make them random or wrong. There are still reasons for emotions, and frequently there's a large degree of truth to them as well. They often do exemplify bias, but that's why there's more than 1 person on the jury, and why attorneys are allowed to disqualify jurors, and why a good attorney will try to get a jury panel that is at least representative of the population if not favorably inclined to her client.

This is not supported at all. I assume you're talking about racial demographics of prison population. It's a complex historical and socioeconomic problem, biased juries may have some role but it wouldn't be on the top 10 factors.
