Let's review:
1) I said repeatedly, "drunk
OR NOT" (the emphasis is new) and I NEVER said he was "inebriated"
2) You insisted he might not have had anything to drink ("though unlikely, it is possible"), despite his own Facebook posting being one of the earliest known elements of this case
3) Now that you know he admitted to drinking, you excuse it because he didn't injure someone.
4) Not every drunk driver injures someone
5) He was at the bar (they sat at stools, remember, the iPhone was left on a stool) for two hours, until closing (which makes it hard to believe the story of the "finder" but that's for another discussion.
I repeat, drunk OR NOT, he did indeed have at least one drink, on his birthday, at a German Beer Haus, and when he left, after two hours when they closed, he did not have the wherewithal to remember his top secret prototype wasn't with him. I don't care if it's drinking, incompetence, or a combination. It's unprofessional. Doesn't excuse the rest of the parties. Plenty of guilt to go around.
