What is the primary responsibility of a defense attorney?

The primary responsibility of a defense attorney is to represent the defendant in legal proceedings. This role involves advocating for the defendant's rights and interests, ensuring that they receive a fair trial, and providing legal guidance throughout the process. A defense attorney is tasked with presenting evidence, arguing on behalf of their client, and working to achieve the best possible outcome, whether that’s through a plea deal or fighting for an acquittal in court.

In the context of a courtroom, the defense attorney plays a crucial role in balancing the justice system by defending individuals accused of crimes. This defense ensures that the legal principles of due process are upheld and that the defendant is afforded every legal protection they are entitled to under the law. Representation by a defense attorney is fundamental to the adversarial system of justice, where both sides have the opportunity to present their case.

The other choices relate to roles that do not constitute the primary responsibility of a defense attorney. Maintaining official records, enforcing courtroom security, and overseeing courtroom procedures are responsibilities typically associated with court clerks or bailiffs, rather than the defense attorney's function.
