My former FIL passed the bar and “practiced” law in rural Kansas back in the 80s-90s. He never attended law school and was self taughtIt's the passing the bar thing. Graduating law school is just part of the process.
I have a friend that was on the Board of Law Examiners in NC for years. After some of the stories I heard, I'm not totally surprised. Some pretty shaky people get past that as well.
