He is willing to admit that it goes over his head, which presumably also means that he'd be willing to read up on it or seek advice if necessary.
The biggest problem isn't judges who doesn't know everything - they have to deal with cases covering every possible discipline and can't possibly know everything about everything put before them. The problem is when they believe they do, or don't care, or don't want to admit it and decides to just trust law enforcement blindly instead.
I'd like to think that a judge that readily admits what he doesn't know will make sure to learn or seek suitable advice when necessary.
