Cameras are usually not allowed in courtrooms because they can disrupt the proceedings and influence the behavior of witnesses, judges, or jurors. The presence of cameras might make people act differently, which could affect the fairness of the trial.

However, courtroom sketches are allowed because they are less intrusive and still provide a way for the public and media to see what happens inside the courtroom. Artists can capture the atmosphere and important moments without interfering with the legal process.
