Randell,
Pick up a copy of Dave Workman's
Washington Gun Rights and Responsibilities booklet. Costs around $10 and you can get it from SAF at
http://www.saf.org/default.asp?p=boo...itle=&bauthor=
Check out
www.useofforce.us for the general overview of lethal force doctrine under common law throughout the United States, or see my website at
www.corneredcat.com/Legal/AOJ.aspx. For similar information of this general nature, see Massad Ayoob's book
In the Gravest Extreme, or sign up for an LFI-1 class taught by Ayoob.
Sign up for a $35 "Handgun Safety Seminar" from the
Firearms Academy of Seattle, which covers the laws regarding gun ownership and lethal force in Washington and Oregon in some detail, and provides you the opportunity to ask specific questions. FAS is located near Chehalis, WA.
Join the
Armed Citizens' Legal Defense Network and take advantage of the DVDs that come with your membership.
The link to specific Washington law provided above is good; as you're perusing that site remember that the criminal codes regarding Murder/Manslaughter/Justifiable Homicide are
not found near the firearms statutes or the statutes related to concealed carry -- be as thorough as you can.
More legal resources are listed on my site at
http://www.corneredcat.com/Legal/resources.aspx; many of them are specific to Washington state.
Hope some of the above helps.
