Honestly, I might get blasted for this, but I dont see the big deal. The President was not in the country so what the heck
"The heck" is are those involved in advanced teams, know codes, movement details, techniques and other sensitive information. All of which could compromise security and the way things are done. If a drunk SS agent was picked up while drunk, abducted, held for ransom, forced to talk, or just have his ID stolen etc., it would not only be a major incident/threat to security but an international incident/embarrassment...
You get it.
“You get it.”
Who cares?
He wouldn't even need to be abducted. All he would need to do is get drunk enough to talk about confidential security matters and not notice that there were people in earshot who may relay the info to hostiles.
I'm not in a profession even close to the sensitivity of Presidential Detail, but even I would never have gotten falling down drunk on a business trip with co-workers. It's just totally unprofessional.
