What Does a Criminal Defense Lawyer Do?
A defense attorney serves a critical role in the criminal justice system by representing individuals accused of committing criminal offenses. Their primary function is to provide a strong and competent defense for their clients. Defense attorneys start by thoroughly investigating the charges and gathering evidence to build a robust defense strategy.
During a trial, defense attorneys work tirelessly to protect their clients' rights. They cross-examine witnesses, challenge the credibility of evidence presented by the prosecution, and present their own evidence and arguments to cast doubt on the accused's guilt. Their ultimate goal is to secure an acquittal for their client or, when appropriate, negotiate favorable plea agreements.
Outside the courtroom, defense attorneys offer legal counsel and guidance to their clients. They explain the legal process, potential consequences, and the available legal options, helping clients make informed decisions about their cases.
Additionally, defense attorneys are vigilant in safeguarding their clients' constitutional rights, including the right to a fair trial, the right to remain silent, and the right to legal representation.
In essence, a defense attorney's role is to be a dedicated advocate, protecting their clients' interests and ensuring that they receive a fair and just legal process, regardless of the charges they face.
Our Laguna Beach attorney understands the sensitive nature of these cases. We are available 24 hours a day, 7 days a week and offer free, confidential consultations. Call

In California, if you hold a professional license and you are arrested or accused of professional misconduct or gross negligence by a patient and/or an employer, you will be the subject of an inquiry that can lead to a formal investigation, in person interviews and on the spot drug and alcohol testing. An inquiry and investigation can lead to potential discplinary action by your regulatory Board, Bureau or Department. In such matters, the respective Board typically empowers an Investigator from the Division of Investigation for the State of California or an Enforcement Analyst of the respective Board to review the subject matter of the arrest or complaint for unprofessional acts or gross negligence whcih can result in an enforcement and/or discliplinary action. This can include a Letter of Reprimand, a Letter of Reproval, a Citation and Fine Order or worse, the filing of a formal Accusation seeking to suspend and/or revoke thelicensee's professional license.
In arrest cases, if you are a licensed professional in California and were booked, meaning you were photographed and fingerprinted, the record of arrest is reported to the Department of Justice for the State of CA ("DOJ"). DOJ then notifies your respective Board of the arrest. An investigation and/or inquiry is triggered and a complaint number, control number or investigation case number is assigned to the matter.
