A criminal defense attorney is a lawyer who specializes in representing individuals accused of crimes. Their primary responsibility is to protect the rights of their clients throughout the legal process, from investigation and arrest to trial and sentencing. They meticulously examine evidence, interview witnesses, negotiate plea bargains, and advocate for their clients in court. A skilled criminal defense attorney ensures a fair trial, challenges unlawful police procedures, and strives to achieve the best possible outcome for their client, whether it's a dismissal of charges, an acquittal, or a reduced sentence.
