The first step in the criminal justice process is the arrest. At this point, law enforcement officers have gathered sufficient evidence or probable cause to believe that a person has committed a crime and detain that individual. This action formally marks the beginning of legal proceedings against the suspect.

Once an arrest occurs, the process continues with further stages, including investigation, charging, and trial. Though investigation is a critical part of law enforcement's efforts to gather evidence and build a case, it typically happens before an arrest and is necessary to establish the grounds for it. On the other hand, trial and sentencing are stages that occur later in the process, after an arrest has been made and legal proceedings have commenced. Therefore, understanding that the arrest is the initiating step helps clarify the progression through the criminal justice system.
