In What the NAACP can learn from George Zimmerman, George Zimmerman's brother Robert Zimmerman Jr. claimed that the organization was slow to act on the beating of homeless African-American Sherman Ware by Justin Collison, the son of a policeman:
My brother George Zimmerman, who lived in Sanford at the time, fought for justice on Ware’s behalf. George tried to enlist the help of the local chapter of the NAACP. He called their office, but they told him that they didn’t have the resources to help.
Collison turned himself in on January 3, 2011. That’s when the NAACP suddenly entered the fray. The same organization that days before hadn’t had the resources to help George announced plans to meet with the new police chief and ask why Collison hadn’t been charged with a hate crime.
Is Robert's description of what the NAACP did and didn't do correct, and the full story, or are there inaccuracies or omissions from this description?
I came across a Media Matters for America blog post mentioning this piece, but it doesn't try to directly rebut the claims.
