Criminal defense law is the practice of representing people and organizations accused of crimes. It spans the full range of offenses, from minor infractions to serious felonies, and the full course of a case — from investigation and arrest through charging, pretrial proceedings, trial, sentencing, and appeal.
A defining principle is the presumption of innocence: an accused person is treated as innocent unless and until the government proves guilt beyond a reasonable doubt, the highest standard in law. Defendants generally have important protections, which can include the right to remain silent, the right to a lawyer, the right to be informed of the charges, the right to challenge the government's evidence and witnesses, and protections against unreasonable searches and improperly obtained evidence.
The work of criminal defense includes advising a client, examining the strength and lawfulness of the government's evidence, identifying possible defenses, negotiating with prosecutors, and, when a case goes to trial, presenting a defense. Many cases are resolved through negotiated agreements rather than trials, but how to proceed is a significant decision that belongs to the accused.
For a non-lawyer, the key point is that the consequences of a criminal case can reach a person's liberty, finances, record, employment, and more. Anyone who is questioned by police, arrested, charged, or under investigation generally benefits from consulting a defense lawyer as early as possible.
