They cleared that up. David Hunt said the 30 seconds was from the time they entered the building which housed Bin Laden until they killed him. Both he and Jennifer Griffin said that was about 20 minutes after the raid began, when they first entered the compound.
I don’t know. If they’re still using the “40 minute on the ground” scenario, that’s halfway into it. That leaves 20 minutes to get the prisoners rounded up, toss the whole place, load everything up and blow up half a helicopter.
I’m more inclined to believe they were in his room closer to the 10 min mark from set down.
