The prosecution has beyond ridiculous arguments time and again over the last 2 weeks. The lawyers all started out really civil, and some of the violations (especially the 5th amendment one that even got the Judge angry) began to make then exasperated.

Combine that with the general silence of the defense, and by now they are all pretty angry at how much of a mess this is.

A lot of ridiculous arguments were brought up by the jury about Rosenbaum, to the point that internal jokes have started emerging surrounding the death of Rosenbaum. Most serve to ridicule the prosecution, rather than Rosenbaum himself.

Lastly, They you are in profession where every time you're in court, some has died. You develop a cruel sense of humor to cope. Very common for victims of abuse or military to have similar coping mechanisms. It seems bizarre from a civilian's POV, but that's just our privilege.
