The best writer I know of was an associate attorney. He didn't have the technical background nor the in depth computer related knowledge, and relying on the information I fed him. But man the briefs he filed to the court were amazingly good. Reading them I would have been convinced his side was right if I were in the jury.
Law LLM will surely help competent lawyers in their fields with greater sources of knowledge not in their core area of expertise.
Sure as long as they stop making things up.
I don't want to imagine a world where juries were responsible for reading briefs and making decisions.
