A "criminal" is a person who breaks the law and commits illegal acts. This can include a wide range of activities, from minor offenses like shoplifting to serious crimes such as robbery or murder. Criminals can face various consequences, including fines, community service, or imprisonment, depending on the severity of their actions. The justice system plays a crucial role in dealing with criminals. It includes law enforcement agencies, like the police, and courts that ensure laws are upheld. Rehabilitation programs may also be offered to help criminals reintegrate into society and reduce the chances of reoffending in the future.
