A lizzie said, there are many factors in why some people are treated favorably and others not so favorably. Does your source compensate for:
-Economic disparities between black and white defendents?
- Other factors in the victim's status rather than race. For example, are proportionally more black murder victims involved in "drug deal gone bad" type situations and thus less appealing to jurors and proscecutors?
-Are white "meth head" vs "meth head" murders also unlikely to elicit alot of effort to pursue death penalties?
-Is the proportion of whites sentenced to death for say, home invasion robbery / murders really disproportionate to blacks convicted of murder in similar circumstances?
