An excerpt:

“Before addressing each of the estate’s arguments, we acknowledge that Davis’s death is tragic and echo the trial court’s sentiment that the application of RCW 4.24.420 here is problematic because it precludes claims where law enforcement officers’ actions and training may have been unreasonable, given their knowledge that the individual they were confronting was suicidal and armed. RCW 4.24.420 prevents courts and juries from reaching the issue of whether law enforcement’s negligence resulted in the loss of life. The statute is clear and precludes our evaluation of these policy questions.”
