Modifying the definition of persistent offender to exclude convictions for offenses committed by someone under the age of 18 and providing for resentencing.

SB 5945 modifies Washington's "persistent offender" definition to exclude convictions for crimes committed before age 18, directly affecting individuals sentenced as adults for juvenile offenses. The bill requires courts to consider resentencing these individuals to align with current constitutional standards established by U.S. Supreme Court rulings (Miller v. Alabama) and Washington state court decisions (State v. Bassett). Key provisions amend sentencing laws to ensure juvenile offenses no longer count toward "persistent offender" status, reflecting scientific understanding that youth have greater potential for rehabilitation. This change applies to people currently incarcerated for such cases, correcting a legal inconsistency where juvenile offenses were still used to impose harsh sentences despite court rulings.
