In a criminal trial, what is the primary role of the defense attorney?

The primary role of the defense attorney in a criminal trial is to cause the jury to doubt the guilt of their client. This responsibility stems from the fundamental principle of the criminal justice system, which operates on the presumption of innocence. The defense attorney's duty is to advocate for their client vigorously, ensuring that all relevant evidence and legal arguments are presented in a way that raises reasonable doubt in the minds of the jurors regarding the prosecution's claims.

This role involves analyzing the evidence, cross-examining witnesses, and presenting any defenses or counterarguments that could challenge the prosecution's case. By creating doubt about the evidence presented against their client, the defense attorney plays a crucial part in upholding the client's rights and ensuring a fair trial.

In contrast, securing a plea deal is just one of many strategies that may be used based on the case’s circumstances, but it is not the overarching role of the defense attorney during a trial. Supporting the victim's claims would be more aligned with the role of the prosecution, which seeks to prove the defendant's guilt. Presenting evidence for the prosecution is also a task designated to the prosecution team, contrasting with the defense's role in challenging that evidence.
