They can't hide it forever..A potential impedachment article may very well come out of this. Nixon was not going to be impeached for a burglary in the Watergate, in which he was knowledgeable. He was going to be impeached for the coverup of that burglary. Nobody died in the Watergate. Several folks went to the slammer. What will happen here, after some American agents have been killed with those weapons.. and several hundred Mexican citizens. ? Just forget it, and say "well, they knew that they were in a dangerous job, and volunteered for it"? Obama has blood all over his hands...you know that because of his Executive Privilkedge over something that he says he has no connection or knowledge of. Stinks worse than a week old dead fish.
