Washington State has an article in the state constitution that guarantees a person the right to bear arms in defense of self or others.
Pretty hard to confuse that one.

From Seattle Times article:
Under state law, a person can use reasonable force to prevent or attempt to prevent injury or “malicious interference” with property in the person’s possession. Force can be used to detain someone who unlawfully enters a building.
Homicide is considered justifiable if the person using deadly force is lawfully defending himself or another person from someone who is committing a felony, or someone who presents an imminent danger, according to state law.
One could make a reasonable argument that the Washington law on the use of deadly force is equal to or maybe even broader than the law in Texas.
