Yes; it usually doesn't end well, and as NoImmatureAdHom notes the rights violation has to rise to the level at which lethal force is justified in self-defense, but it does happen and people get cleared of the inevitable charges, that's happened in my home town although the shooting did not kill the officer. And armenarmen's link doesn't include the case where black grandmother was killed in her dwelling, that didn't end well for the police.
