I used to think that the contempt they are showing was because of their grief and the horrific situation they are in, but after the depos I am convinced that their contempt is just a demonstration of what kind of people they are. I find them to be untruthful, combative, control freaks, and I will guess anti social. From what we have seen they have no social circle, no family and or friends speaking to demonstrate they are anything other than they have portrayed themselves to be....hostile, agressive, disingenuous people.
Yes their behavior is hurting the defense, but I don't know how to vote why here.
