2. Officers Make Arrests with Probable Cause (RCW 10.31.100)

A police officer will arrest and take into custody, pending release on bail, personal recognizance, or court order, a person without a warrant when the officer has probable cause to believe that:

Assault-Mandatory Arrests:

A mandatory arrest is required under RCW 10.31.100(2)(c) when these factors are present:

- The person is eighteen years or older and within the preceding four hours has assaulted a family or household member as defined in RCW 10.99.020 and the officer believes:

- A felonious assault has occurred;

- An assault has occurred which has resulted in bodily injury to the victim, whether the injury is observable by the responding officer or not; or

- That any physical action has occurred which was intended to cause another person reasonably to fear imminent serious bodily injury or death.

- Bodily injury means physical pain, illness, or an impairment of physical condition. When the officer has probable cause to believe that family or household members have assaulted each other, the officer does not have to arrest both persons. The officer will arrest the person whom the officer believes to be the primary physical aggressor.

- In making this determination of the primary physical aggressor, the officer will try to consider:

- That the primary physical aggressor is not always the person who struck first

- The intent to protect victims of domestic violence under RCW 10.99.010;

- The comparative extent of injuries inflicted or serious threats creating fear of physical injury; and

- The history of domestic violence of each person involved, including whether the conduct was part of an ongoing pattern of abuse.
