Yes, I heard a news report this morning where the actual SEAL guys were sourced as saying he was not armed. I mean it was all business, anyone on that compound is a legitimate target, armed or otherwise, as far as they were concerned. There was some initial enemy fire, but once they were in the house, no one was armed. They just weren't expecting anything.
I am a peaceful person, but I do have firearms, that are not far from me at anytime in my home and no world superpower wants me dead. He must have had some pretty ironclad assurances he was safe.
And now I am also wondering if he actually is dead. SEALs are disciplined, they wouldn't just double tap a bad guy out of spite (which is how the report suggests it happened). Better to just grab him, kill all the witnesses and tell the world he's on the ocean floor and it's a nice tidy story.
