Since mid century and on, you see how the line of reasoning "if I am allowed to do that, it's right" and legal casuistics completely hollowed out the moral integrity of American judiciary.
My business law prof was a lawyer who began his career as a trial lawyer in USA, and then moved to Canada. One of reasons he said made him drop it was him feeling despair every time he saw judges spending court breaks smoking with prosecutors, and giving him a gawking look when they saw him looking at them. He said he felt that judges and prosecutors were pretty much teaming up on poor defendants, and that he had to fight courts as much as the prosecution side.
He was one of defence lawyers for black rights movement, panthers and poorer black people, during seventies. He was one of youngest lawyers around back then, and he ended up defending such cases because nobody more senior in the defence lawyer community wanted to take upon such "hopeless" cases.
How would you not call such legal system a joke? How can it pretend having any decorum?
