A new type of audit
The Office of the Washington State Auditor conducts audits of investigations into police use of deadly force. We do this to ensure compliance with accountability rules established by voter-approved Initiative 940 and the Legislature.

Key components of an investigation
These investigations, conducted by an independent investigation team known as an IIT, may include multiple steps. They include: gathering evidence; reviewing results of an autopsy; and reviewing results of crime lab reports. Completing investigations may be delayed because of backlogs at crime labs.
What our audits will examine
We will evaluate four aspects of each investigation: Was it credible? Was it independent? Was it transparent? Was it communicated to the public and affected people? To determine this, we will compare the steps taken by the involved law enforcement agencies and the IITs to the standards set by the state Criminal Justice Training Commission.

Our work will not determine whether the officers were justified in using force, nor whether prosecutors made the right choice to charge or not charge officers with a crime.
