I’ll put it a different way
If in court A says but why didn’t C do whats asked of A, the court reporter will be instructed to omit that comment from records. They are not there to discuss the wrongs of others not mentioned in the suit, we are here to decide if A is guilty of said crime or not. Period.
If its not going to be a deciding factor why am I wasting time out of my life, I will never get back, on it?
The court decides, I go by their requirements. Anything else is wasted time.
