In Israel, we do not have juries, but a panel of three judges sit on criminal cases. I have found that most of the players in the real court-room dramas are sincere and doing the best they can.
Prosecutors try to put away the bad guys and the defense lawyers do what they were hired to do - get the accused off or with the lightest possible sentence. Defense lawyers are not defendants of justice but of accused men and women, some of whom are truly guilty. As such, when I have been approached by defense lawyers asking if I would serve as an expert witness, most do not call me back when I tell them that I will only testify to what I see and I will not bend the truth of what I see even a smidgen.
When I have been brought into court as expert witness, I have found that the judges do want to understand the psychological elements at play and they weigh what I say up against traditional legal evidential rules. Given my clinical experience with survivors of sexual trauma, perpetrators, and their families, I have been able to point out to the court aspects of survivor and perpetrator behaviors to which they would not have paid any attention.
Lawyers and judges are people with their own individual histories, biases and beliefs. I wonder how many of them have, themselves, or someone close to them, experienced sexual trauma. I wonder how their own experiences with sexual trauma affects their decision making processes in court.
It is true that lawyers, whether for the defense or the prosecution, will work harder for people they like and may even be lazy when they do not like the individual on whose behalf they are supposed to be working.
I have seen judges find a defendant not guilty, and a head prosecutor not take a case to trial, just because they were not yet able to conceive that, on the one hand, a father could sexually abuse his son and, on the other hand, a mother could sexually abuse her children.
These happened many years ago and the courts today are more prepared to handle such cases. Just as they are more able to run calm and thoughtful trials of sexual harassment in the workplace (even involving famous suspects), cases of wife rape and acquaintance rape - issues that were not well handled in the past.
