Where was his security detail or Secret Service attachment? As the son of a Vice President, doesn't he represent a high value target for things like kidnapping and espionage? Was he doing all these things unprotected and untracked by anyone with his or the country's security in mind?
No one seems to be asking these questions when the answers could indicate a lot of interesting (and concerning) things.
I started wondering about this myself. We know some agents have come forward to talk about Joe's inappropriate behavior (swimming naked in front of female agents and inappropriately touching agents' wives).
