Under growing public pressure, the Department of Justice announced Monday that it would conduct a review of the case, but added the qualification that the “government must prove beyond a reasonable doubt that a person acted intentionally with the specific intent to do something which the law forbids.”
Complicating matters, Florida state law allows a person the right to stand their ground and use deadly force if they feel threatened. The Justice Department recognized that, stating that “negligence, recklessness, mistakes and accidents are not prosecutable under the federal criminal civil rights laws.”
The federal government can’t prosecute Zimmerman for murder or manslaughter, so any prosecution for civil rights violations must prove Zimmerman took Martin’s life because of prejudice.
Zimmerman’s family denied he is a racist.

Martin had no weapon and was much smaller and weaker.
The "stand your ground" law pretty much works against Zimmerman.
