Attorney General Eric Holder rallied with Al Sharpton, whose activism in the Trayon Martin case is well-known, to promise "a thorough and independent review" of the case.
Holder invoked the most powerful images of the civil rights era before discussing Martin. "'Only when it is dark enough,' Dr. King said, 'can you see the stars,'" Holder told the crowd at Sharpton's annual National Action Network Convention, per prepared remarks. "Today, once again, it is dark enough."
"If we find evidence of a potential federal criminal civil rights crime, we will take appropriate action," Holder added. "And, at every step, the facts and the law will guide us forward," he added.
Al Sharpton, Holder's host, has called for an "escalation" in civil disobedience if George Zimmerman -- the shooter in the Trayvon Martin case who said he acted in self-defense -- is not arrested.
