I think the answer is yes from my interpretation of RCW 9.41.270 which reads in part:

(1) It shall be unlawful for any person to carry, exhibit, display, or draw any firearm, dagger, sword, knife or other cutting or stabbing instrument, club, or any other weapon apparently capable of producing bodily harm, in a manner, under circumstances, and at a time and place that either manifests an intent to intimidate another or that warrants alarm for the safety of other persons.

I'll be in Vancouver next week for a conference, I plan to carry one of these (hidden in my shorts) for dog repellent while jogging:

As long as I don't "...intimidate another or that warrants alarm for the safety of other persons..." can I carry a concealed ASP in WA?

Is that an expanded baton in your pants, or are you just happy to see me?

Look for the Definitions section, or something like it, in the WA statutes, and see the definition of "club." If there is no definition, start poring through the law books for a precedent-setting case.

In Texas, FWIW, an ASP baton is, indeed, a club. Baton = Club. Same-Same. Being collapsible does not alter this. WA, of course, may vary from Texas in this regard.

Then, there is the matter of intimidating and alarming. Again, look for case law, if there are no clear definitions in the statutes.

Actually, if unsure, I think I could survive a weekend without going jogging.

I know it's late, but they are legal.
