The feds can only prosecute under the Civil Rights Act if someone violates another's civil rights while carrying out their gov't duties, as the LA cops did (or didn't), or when clearly established that a person was deliberately targeted because of their race, color, etc. Zimmerman did neither. A jury already decided that he didn't profile/target Zimmerman because he was black. If the Feds try him, it IS double jeopardy. But Obama and his thugs never let little things like the Constitution and the law stand in their way.
