This is a rather mundane observation.
Or are you misreading this to imply the captain knew from the very beginning he was a real SS agent? It seems so! 
So you think the captain is saying his questioning of documents was frivolous, since he knew anyway. No, that's the position of the other press release. Guess you should read your own link again.

Let me clarify. You said the Captain had every right to interrogate the Secret Service agent because he needs to be sure the agent is not a fake. What I am saying is that is not the reason the Captain interrogated the Secret Service agent, because the Captain was convinced by the Maryland Airport Authority police that the agent was for real.
The next step is to find out the real reason for the Captain's interrogation, now that we know that the agent's identity ceased to be an issue at some point during the interrogation.
