An arrest is the physical or constructive confinement of a person by police officers based on probable cause (Fourth Amendment). Upon arrest, law enforcement officers restrict your liberty and initiate administrative booking. The Federal Rules of Criminal Procedure (FRCP) 5(a) mandate that arrests be made without a warrant and that the arrested person be promptly taken before a magistrate. State jurisdictions have similar statutory requirements to appear before a magistrate. Penal Code Section (PEN) 825 provides that an arrested person must be brought before a magistrate without unnecessary delay and within 48 hours of arrest, excluding holidays and weekends. Charges are a formal, written accusation by the prosecution that sets out the particular criminal law(s) alleged to have been violated and the statute(s) under which you are being prosecuted.
Understanding where you stand legally after an interaction with law enforcement is critical. The information below breaks down the exact differences between being arrested by police and facing formal charges from a prosecutor, along with what you need to know about your rights and pretrial release.
Understanding the Arrest Process
An arrest is the first time a police officer uses physical or legal arrest powers to confine a person to the agency's custody. This encounter starts the police processing and investigation.
An arrest occurs when a police officer stops a person, and that individual is no longer free to leave. This happens when an officer physically restrains you (like using handcuffs) or orders you to stop, and you comply, officially bringing you into police custody. While police officers may make an arrest without a warrant, they must have specific, articulable facts establishing probable cause as required by the Fourth Amendment and judicial interpretations. If the detention is not based on probable cause, subsequent detentions are unconstitutional and violate the protections against unreasonable seizures granted by the U.S. Constitution. IV.
The Fourth Amendment requires that all lawful arrests be made upon the basis of probable cause. Prosecuting officers need reliable information and circumstances that would lead a reasonable person to suspect that you have committed or are committing a crime. At the scene, police officers collect evidence, interview witnesses, and assess the evidence to determine this threshold. The exclusionary rule in Mapp v. Ohio, 367 U.S. 643 (1961), and Weeks v. United States, 232 U.S. 383 (1914), can affect the admissibility of evidence in court when officers lack probable cause at the time of arrest.
After making an arrest, police officers will bring you to the local police station or holding center for booking, as required by administrative law enforcement procedures. The booking procedure involves:
- Recording your personal data
- Recording the suspected offense
- Taking fingerprint impressions and your photos
During this stage, law enforcement inventories your personal property. Once booking is complete, you will remain in a holding cell until your initial court appearance and bail determination.
What It Means to Be Formally Charged
While police officers handle the physical arrest, prosecutors make the ultimate decision on whether to file formal charges based on their own review of the case. This separation is a significant change in legal proceedings.
Article XI, Section 1 of the California Constitution and California Government Code Section 26500 give the public prosecutor the exclusive authority to initiate and conduct criminal prosecutions on behalf of the people. When police officers finish investigating and preparing reports, a prosecuting attorney examines the case file. The prosecutor determines whether there is sufficient evidence to prove a crime and whether a criminal conviction is likely based on the charging guidelines and the burden of proof required for the crime. The prosecutor is free to decline to file charges (prosecutorial discretion), even if the police have made an arrest. This is likely if the evidence is lacking.
The classification of criminal charges is done according to the gravity of the alleged offense under the statutory penal codes. Misdemeanors are less serious crimes punishable by county jail time or fines. On the other hand, felonies are more serious offenses punishable by imprisonment in state prison or county jail. Also, minor violations or citations are handled through a summary process, and there is no typical police arrest for this violation. The classification determines the proceedings that your case will go through in the court system.
If a prosecutor files a formal criminal complaint or an information under PEN 739 or secures an indictment pursuant to PEN 917, the case moves to the judicial phase. The formal reading of charges and entry of a plea occur at an arraignment. This hearing will let you know:
- What you are charged with
- Your rights under the Sixth Amendment
- What penalties you may face for the charges
The charging process officially begins when charges are filed.
Key Comparisons Between an Arrest and a Charge
The difference between an arrest and a formal charge can help determine which stage of a criminal case the arrest is in. These two events may occur one after another, but they are totally separate and distinct legal processes under different authorities and rules under the statute and the Constitution.
While charges are usually formulated by prosecutors in an office environment based on law enforcement officers' determination of the legal sufficiency of an action in an active field investigation, charges can also be formulated by law enforcement officers during an active investigation. This distinction also has a direct impact on the evidentiary standards: probable cause at the time of arrest (Fourth Amendment) versus proof of guilt beyond a reasonable doubt.
Furthermore, the formal documentation varies greatly from one case to the next: police use booking records and incident logs to document an arrest, while prosecutors use formal criminal complaints or indictments, as outlined in Federal Rules of Criminal Procedure 3 and 7. Thus, legal outcomes can diverge, allowing you to be arrested even after an independent prosecutorial review without prosecutors ever filing formal charges. This shift has significant procedural consequences: a clear transfer of responsibility from executive law enforcement custody to the judicial system, as mandated by separation of powers principles.
Navigating Release Options and Pretrial Freedom
In the immediate aftermath of an arrest, your top priority is securing your pretrial release so you can prepare for your court defense from home. There are pretrial release mechanisms that allow return to the home environment, with the case moving through the system on the condition that the requirements under PEN 1275 are met.
You can be released on your own recognizance or with monetary conditions (bail). If cash bail requirements are set higher than the financial means of the party, using a professional bail bond service offers a feasible solution to get out of jail and get ready for court appearances away from jail walls.
