All of you who have posted have good points. What disturbs me even more is the fact that both Holder and Obama have denied knowledge of this fiasco. Whatever happened to Harry S. Truman's sign, "The buck stops here"?
It has always been my understanding that the ultimate responsibility for an action, or lack thereof, rests on the shoulders of the person in charge. Holder, as Attorney General, should have been well aware of what was going on. Obama, as President, should have gotten daily briefings on the progress of such an unorthodox operation. The fact that both are claiming complete ignorance of this mess is, in my eyes, evidence of dereliction of duty.
Holder, because of that dereliction, should be fired by Obama. Obama, again because of his dereliction of duty, should be "fired" by being voted out of office. Obama's offense in this particular case, unfortunately, did not rise to the level required by the Constitution for impeachment. I am not too sure that the deaths of innocent people and law enforcement officials directly linked to this operation should not be cause for criminal complaints up to at least the level of Attorney General.
