Domestic violence calls are challenging and highly emotional situations for Maryland police officers. Contrary to common assumptions, officers do not base arrest decisions on who is more upset, who called 911 first, or who simply “seems right.”
Instead, Maryland law sets specific legal standards that guide whether an arrest will be made at the scene of an alleged domestic assault.
Below is a clear explanation of how police make these decisions.
Key Legal Standards for Arrest
Maryland does not have a mandatory arrest law for every domestic violence call. Officers must first establish probable cause, meaning there is reasonable, articulable evidence that:
- A crime occurred, and
- A specific person committed it
Police may make a warrantless arrest for assault if they have probable cause and believe the suspect is likely to:
- Flee
- Destroy evidence
- Cause further injury
- Pose an ongoing danger to the victim
Evidence Police Consider When Making an Arrest
To determine whether probable cause exists, officers typically rely on a combination of evidence, including:
- Physical Evidence
- Visible injuries such as bruising, swelling, or redness
- Broken property or signs of a struggle
- Statements
- Accounts from the involved parties
- Statements from independent witnesses such as neighbors or children
- History of the Location or Parties
- Prior police calls or documented incidents
- Other Documentation
- Doorbell camera footage
- Cell phone videos or recordings
- Demeanor and Credibility
- Consistency of statements
- Behavior of the parties at the scene
An arrest may still occur without visible injuries if other evidence supports that an assault took place.
Mutual Allegations and the “Primary Aggressor”
Domestic incidents frequently involve mutual accusations. In these situations, Maryland police are trained to identify the primary aggressor—the person most responsible for the physical violence.
Factors officers evaluate include:
- The severity and type of injuries sustained by each person
- Evidence of self-defense
- Physical size, strength, and ability of each party
- History of abuse or prior complaints
- Witness statements
- Threats made before police arrived
Maryland law enforcement policy discourages dual arrests (arresting both parties) unless absolutely necessary.
When Arrest Is Mandatory in Maryland
Officers must make an arrest when:
- There is probable cause for a felony assault, such as strangulation or serious bodily injury
- The assault occurred in the officer’s presence
- The suspect violated a Protective Order or Peace Order within Maryland
When Police May Decline to Arrest
Officers may choose not to arrest when:
- Evidence is conflicting or insufficient
- There is no clear primary aggressor
- Both parties appear equally aggressive
- The incident did not rise to the level of an assault
- There are no injuries and no corroborating evidence
In these situations, officers may separate the parties or advise them about seeking a Protective Order through the court system.
Post-Incident Options and Legal Rights
An arrest does not guarantee a conviction. Many domestic violence cases are dismissed or resolved without a guilty finding after further review.
If police do not make an arrest, alleged victims may still:
- File for a Protective Order
- File criminal charges with a Maryland District Court Commissioner
- Consult an attorney regarding safety planning and evidence preservation
Conclusion
Domestic violence arrest decisions in Maryland are based on probable cause, identification of the primary aggressor, and whether any court orders were violated.
Whether you are the accused or the alleged victim, consulting an attorney experienced in Maryland domestic violence law is critical to protecting your rights and ensuring your safety.
