Summary:  Nilgün Aykent Zahour analyzes the juror misconduct issues in the case of State v. Arndt, 426 P.3d 804 (Wash. Ct. App. 2018).  The issues we address are: Internet research on Google and Wikipedia to find a definition of premeditation, the presumption of prejudice and whether that presumption can be overcome or rebutted, credibility determinations at an evidentiary hearing, and a working definition of the abuse of discretion standard of review.
