I have a neighbor who is 89 YO, and still keeps up his dues to the Bar for his law license. (Those egomaniacs NEVER give up their license.. (hasn't practiced in years)
I find it fascinating that two of the most preeminent Barrister / law professors of our time, only had their credentials for a few years before "retiring" from the practice of law.
Of course a Manchurian candidate would hardly need anything as inconsequential as a law license to be elected to the highest office in the land.
