These gunners wither away and become normal, despite having gone to law school, and they become replaced.

who never had the audacity to be a gunner in law school, become your stereotypical lawyer

Do not be fooled with people in the legal profession, or any other profession, who try hard to sound smart by using, for example, "par excellence" and "since time immemorial" in the same sentenced stuffed with legalese. It's OK if every now and then people get "rewarded" for no merit if that means they will shut up, as long as they know that we are in on their game, and that they'll have to change eventually into mature adults.
