You're not the cops I've dealt with but thanks for being good sports when I go hard on you guys when you falsely arrest me and stuff. Eventually the realization dawns that I am rich and will fight back (I don't look it, drive an old car, wear old clothes) and magically the charges go away. Occasionally, I have to prove one of you perjured yourself.
This makes me wonder how much of legal decision-making is based on the actual law and the arguments being made, and how much is based on one's adherence to proper "courtroom culture" demonstrating that you're sophisticated enough to warrant bargaining with, rather than dictated to.
