no, you're not understanding me. I'm not making any claim on whether they're any good at those subjects, merely that they are, objectively, trained on them

What is the relevance of this claim on its own if training on something alone is not sufficient for them to practice law, and you actually have to add cross-domain into picture for it to work, making it "general"?

I still disagree though, they are not trained to practice law. They are trained to remember law, but practice come from general training to follow instructions.
