The Obama administration is STOPPING the FBI from going to Benghazi and doing an investigation. That's the FBI's job... they investigate - and they're being stopped. Just like the potential rescuers were stopped. By the time the FBI is allowed there, CNN will have walked off with anything interesting and our enemies will have planted a new story - or destroyed evidence of what happened - or both... or neither. We might never know.
It reminds me of the mess after Katrina - New Orleans was going under - - cops were unable to work 14 hour days... and ALL over the country, police departments were standing by - totally ready to go to New Orleans BUT they had to wait to be invited. They had to stay within the law. For example, Chicago's police force can't come down to Orlando and start arresting Disney tourists... they aren't allowed. Laws, procedures, chains of command... all the stuff that makes us civilized. Well, civilized if the people at the top are ethical and even mildly 'with it'....
I think the FBI story was just lip service to the voters. I haven't been able to figure the logic behind sending the FBI over there. What are they going to find out that Zero's Czars didn't already see near real time from the drone and from the compound closed circuit cameras?
