The good folks at the ACLU of Washington explain why the state's death penalty system is a mess here, here, here, and here.
You can see proposed legislation to address the issue here. And you can easily encourage your legislators to support the plan here.
As with all other movements for civil rights, this will not happen overnight. Modest as it may be, however (phone call, letter, buzz in a legislator's ear at a public meeting, etc.), this is the stuff that builds toward change.
Take a moment to contact your legislators, put a but in the ear of friends and family, and cross your fingers...
Thank you for all you do.
