Our day in court

Years ago, my mother passed a stop sign. A policeman pulled her over and she went on to explain that she hadn't seen the sign, to no avail.
My father took pictures of the sign which was not visible to my mother, due to the foliage which had obstructed her view.
My mother's day in court arrived and my father had his day in court, cross examining the policeman, asking questions about the angle where he was standing from the stop sign and so on.
After his interrogating the policeman, my father introduced the pictures he took into evidence.
The judge took one look at the pictures and asked my father, "Why didn't you show this to me in the first place? Case dismissed."
I thought of the incident when I read Rabbi Yaakov Salomon's article at Aish.com about his day in traffic court.
He described his feelings in court as follows.

"I started feeling a bit light-headed and a slight quiver emerged on my bottom lip.
Wow, I thought, I am really nervous about this thing. How absurd is that?"

As I was reading the article, I couldn't help but think that if the author of the article was nervous about a day in court regarding a traffic violation, can we imagine how much more nervous we will be at our day in court after 120 years?
How about if we spend the rest of our ad meah veesrim shana in building up a strong defense in the most important case yet to come?
