I have always felt that it is better to earn 7 points in ten minutes than earn 10 points in two hours. The key thing to remember is to have a theme to your case. While the charge tells why the person is technically guilty, the theme tells the judge why you are right . Once you have proved the basic elements of your charge, concentrate on evidence that persuasively supports your theme. Don't object to irrelevant evidence unless it hurts you .
Most judges hate objections.
They require more work and make you look like you are hiding something. Most irrelevant evidence is harmless. Therefore, there is no purpose in objecting to it. If the other side wants to bore the judge with meaningless garbage, why should you want to stop them. When in doubt, include it in you initial submission .
