Judge Rollis a Federal Judge! Who the Hell is Holder or his minions to discount that Judge Roll was there in His Federal Capacities!! If he was a Demorat Appointed Judge, You can bet the story woulda had him being a Liberal Hero who saved Hundreds while being attacked by a Rightwing Extremist!
With the RATS ‘leading’ this investigation, it may boil down to whether he was wearing or carrying his robe or not.
Loughner was charged with Judge Roll's murder upon being taken into federal custody, but they dropped that charge from the indictment. I have no problem with that - if Congresswoman Giffords had been shot while pushing a shopping cart inside that Safeway (instead of at an organized event), it'd be difficult to say she was injured during the course and scope of her duties.
I don't think this is about Democrats vs. Republicans; it's about the U.S. Attorney not looking incompetent when the defense gets charges dismissed. Let the State of Arizona run a concurrent prosecution - it's the way the system is supposed to work.
