When making this statement:

> "That the most important witness in the case [Levandowski], somehow his own files got overlooked. That's very suspicious."

I think the judge was specifically referring to this fact:

> Uber also said, just this weekend, that it found that Levandowski's e-mails from his startup, Otto Trucking, hadn't been properly migrated to Uber and weren't produced.

So I read it as he's raising the Vulcan eyebrow at Uber for that.
