Eric Garner's death is a tragedy, but federal civil rights law has a narrow focus, one that may make it hard to bring criminal charges.

Federal law prohibits police officers from willfully depriving people of their constitutional rights. A police use of force is a federal crime only if an officer intentionally uses excessive force. Proving "willfulness" is often the biggest obstacle to federal prosecution. If an officer genuinely believed the force he used was necessary, he is not guilty of a federal crime, even if he was wrong.
