They are still milking the Trayvon Martin shooting even though there is absolutely no doubt that Martin attacked Zimmerman without provocation and was beating Zimmerman's head on the ground when Zimmerman shot him in self defense. The prosecution's own witnesses established these facts.
Holder will find nothing in Ferguson but will by federal might force a consent decree, in effect commandeering the Ferguson PD.
Meanwhile he continues his fishing expedition against Zimmerman. Having this “investigation” open for years is defamatory.
