It may seem smart to resist the urge to show literally everyone you meet your badge. However, this is not the right way to do it. Before you do anything else, always show the person your badge. This proves that you are in fact an attorney. Also, it may be helpful to present this during witness testimony. If you're penalized for this action, you just didn't do it right and should try it again.

When you see a contradiction in a witness' statement, yell "objection" as loud as you can. Also do your most dramatic point. After making a sufficient objection, rub your evidence in the face of the witness. Also pray that the prosecutor doesn't present an updated autopsy report.

This can also be applied to your objection. Because after all, what cross examination wouldn't be complete with the DESK SLAM? Show the prosecution and the actual killer that you mean business. Pound that desk as hard as you can. Assert your dominance in the courtroom. If you master the desk slam, the perp will quiver in fear and confess to everything.

Once you master all of these elements, you're sure to get an acquittal for your client.
