This is a court sketch of O.J Simpson. These kinds of sketches allow the media to understand what is going on in the courtroom when no cameras are allowed. Media outlets depend on these sketches when no media is allowed inside.
This is a good example of a court sketch representing the trial of the Aurora shooting case back in July of 2012. Cameras were not directly allowed inside the courtroom during the trial so a drawing expert was called in to sketch an image from the scene of the trial More about court sketches and why they are used at http://justinmuir.hubpages.com/hub/Why-Do-Courts-Use-Courtroom-Sketch-Artists
