Everyone needs to be held accoutable for their actions. If holder didnt know about this it shows his lack of leadership and his inability to do this job and he should step down. If he did know about this (and I think he and obama both knew) then he should be tried for it. Congress has the power to impeach a president I am sure they could impeach Holder. This operation not only put firearms in the hands of violent cartel gangs and resulted in who knows how many murders, they are breaking treaties by allowing illegal arms trades to take place. These lower individuals would not have the ability to pull this kind of operation without approval from higher ups. They all need to be held accoutable from Obama on down.
