How Mandatory Arrest Works in Arizona
When someone calls 911 to report a domestic dispute in Phoenix, Scottsdale, Mesa, Tempe, Chandler, Gilbert, or anywhere in Arizona, the responding officers are operating under a mandatory arrest framework. Under ARS § 13-3601(B), if a law enforcement officer responds to a domestic violence call and has probable cause to believe that a DV offense has been committed, the officer shall arrest the person suspected of committing the offense.
The word “shall” is critical — it removes officer discretion. Unlike most criminal scenarios where officers can choose whether to make an arrest, DV calls in Arizona mandate that someone goes to jail if the officer finds probable cause. This policy was implemented to protect victims of domestic violence from situations where abusers would convince officers not to make an arrest. But in practice, it also means that people who are falsely accused or who were defending themselves get arrested based on preliminary information that may be incomplete or inaccurate.
The Primary Aggressor Determination
How Officers Decide Who Gets Arrested
When officers arrive at a DV scene and both parties are present, they must determine who is the “primary aggressor.” Arizona law directs officers to consider several factors including who called 911, as the caller is often initially perceived as the victim. They look at the comparative severity of injuries suffered by each person. They evaluate each party’s statements about what happened. They consider the likelihood of future injury to each person. They assess whether either party acted in self-defense. They observe the emotional state of each person — who appears fearful versus calm.
Problems with the Primary Aggressor Analysis
The primary aggressor determination is made quickly, at the scene, based on limited information. Officers arrive to a chaotic situation, hear two conflicting stories, and must make a judgment call. This process is inherently imperfect. The person who called 911 first has an advantage, as their version of events frames the initial narrative. Visible injuries may not tell the full story — the person with fewer injuries may have been the aggressor. Emotional presentation is unreliable because some people respond to stress with tears and fear while others respond with calm, and neither response correlates with guilt or innocence.
What Happens After the Mandatory Arrest
Booking and Release Conditions
After arrest, you will be transported to the local city jail or the Maricopa County 4th Avenue Jail depending on the charging agency and severity. At the initial appearance, the judge will set release conditions that typically include a no-contact order prohibiting all communication with the alleged victim, a requirement to stay away from the shared residence, prohibition on possessing firearms, and potential supervision requirements. These conditions are imposed before you have had any opportunity to present your defense.
The Prosecution Takes Over
Once charges are filed, the case belongs to the city prosecutor (for misdemeanors) or the Maricopa County Attorney’s Office (for felonies). The alleged victim does not control whether the case proceeds — the prosecution makes that decision based on the evidence available.
Challenging the Mandatory Arrest
Challenging Probable Cause
The mandatory arrest policy requires probable cause. If the officer lacked probable cause to believe a DV offense occurred, the arrest may be invalid. Attorney Josh reviews body camera footage, officer reports, and witness statements to determine whether probable cause existed.
Challenging the Primary Aggressor Determination
If the officer arrested the wrong person — if you were actually the victim or were acting in self-defense — the determination can be challenged. Evidence including prior threats by the other party, injuries consistent with self-defense, and surveillance footage showing the sequence of events can demonstrate the officer made the wrong call.
Body Camera Footage
Arizona law enforcement officers are typically equipped with body cameras that activate upon arrival at DV calls. This footage captures what officers observed, what each party said, and how the determination was made. Attorney Josh obtains and analyzes body camera footage in every DV case.
Your Rights During a DV Investigation
When officers arrive at a DV call, you have the right to remain silent. You are not required to make a statement, and anything you say will be used in the arrest determination and in the prosecution’s case. While remaining silent may feel counterintuitive when you want to tell your side, anything you say at the scene — while emotional, possibly intoxicated, and under extreme stress — becomes evidence.
Attorney Josh advises clients to provide basic identifying information but to assert their right to remain silent regarding the details of the incident. You can tell the officer that you will cooperate but wish to speak with an attorney before making a statement.
How Mandatory Arrest Affects Your Defense
The mandatory arrest policy means that your defense begins at a disadvantage — you have already been arrested, charged, and subjected to release conditions before your attorney enters the picture. This makes early legal intervention critical.
Attorney Josh begins building the defense immediately by obtaining body camera footage and police reports, identifying and interviewing witnesses, preserving digital evidence, analyzing the probable cause determination, and preparing challenges to the primary aggressor analysis. The goal is to shift the narrative from the one-sided account that led to your arrest to a complete picture.
Common Questions About Mandatory Arrest Policies
Can the officer choose not to arrest anyone?
If the officer determines that no DV offense occurred — that there is no probable cause — they are not required to make an arrest. However, officers err on the side of arrest because failing to act in a genuine DV situation creates liability.
What if both of us say nothing happened?
Officers are trained to look beyond the parties’ statements. Even if both people deny anything occurred, visible injuries, property damage, or other evidence can provide probable cause.
Can I refuse to open the door for police?
If officers have probable cause to believe a DV offense is occurring, they may enter the residence without a warrant under exigent circumstances. Refusing to cooperate can escalate the situation but does not automatically waive your constitutional rights.
What if I was the one who called 911?
Calling 911 does not guarantee that you will not be arrested. If officers determine that you were the primary aggressor, you can be arrested even though you initiated the call.
