The Post’s coverage of the Libya attack was good early and good late, but there was an unfortunate gap in the middle — partly but not completely explained by personnel issues — that made it look like The Post was shying away from a full-court press to find out what the Obama administration knew and whether it was giving a true portrayal of the attack. …
