Exactly why is Holder supposed to do anything about it? If he is found, in any city or State to be in posession of a firearm and he isn't doesn't have a permit for it then arrest him. What is the big deal here and why blame Holder?

As far as his statement regarding Zimmerman, that was his personal feelings and not all member of the Black Panters agreed with it. One of its leaders was on HLN and said he wasn't in agreement with it and that it was a stupid thing to say and only muddied the waters.
