pretty much. I think they are like lawyers on opposite sides of a trial. At the end someone goes to jail an they go for drinks.
And its no coincidence that so many in public office are trained as lawyers.
The funny thing is, most lawyers are at least somewhat skillful in mediation. Althoiugh I've been surprised both ways; lawyers who love trial but show themselves to be good at handling a dispute between people, and lawyers who do a lot of out of court settlement but continue the gamesmanship when they should be working toward solution. Go figure.
