It is not the case, as the conservative blog The Daily Caller argues, that Florida blacks "benefit" from the state's "stand your ground" law. The site's article—"Blacks benefit from Florida 'Stand Your Ground' law at disproportionate rate"—masks the reality: That killings by black perpetrators are more likely to be found justified under the law in part because their victims also are black.
The Daily Caller used a Tampa Bay Times database for its analysis, finding:
Black Floridians have made about a third of the state’s total “Stand Your Ground” claims in homicide cases, a rate nearly double the black percentage of Florida’s population. The majority of those claims have been successful, a success rate that exceeds that for Florida whites.
Nonetheless, prominent African Americans including Holder and “Ebony and Ivory” singer Stevie Wonder, who has vowed not to perform in the Sunshine State until the law is revoked, have made “Stand Your Ground” a central part of the Trayvon Martin controversy.
It's clearly not the case that the law, which allows those who fear for their lives to use deadly force in response, is at the center of the Trayvon Martin case due to Holder and Wonder's post hoc comments. But the more egregious error is in the first paragraph.
