I'm never sure I want to wade into these discussions, but here goes . . .
The meaning of the statute is largely dependent on how it is dissected. If the statute had been written in a slightly different format, it might be more clear. Consider this, for example:
(b) Every licensee shall have his or her concealed pistol license in his or her immediate possession at all times that he or she is required by this section to have a concealed pistol license and shall display the same
(i) upondemand to any police officer or
(ii) to any other person when and if required by law to do so.
Was this the intent of the legislature when writing this bill? Remember that the legislators don't write the bills or statutes, staff and the Code Reviser's Office do (and staff are often junior attorneys). They have to try to capture the legislative intent in sometimes complex and clumsy language.
Reading statutes and drafting this type of language is part of my work. When I read 9.41.050, it seems logical to me that the intent of the language is as I have broken it down above. Had there been three required circumstances for display of a CPL, they would have been enumerated, however with only two they are simply joined bythe conjunction "or." It would have been much more clear if they had inserted a comma after the word "officer."
If they had intended to make display to a police officer required only when specified somewhere else in law, it would have read:
. .. upondemand to any police officer, or any other person, when and if required by law to do so.
The punctuation makes all the difference, and unfortunately the subtleties are not always dissected until something goes to court and the fine points are argued or a judge makes an interpretation.
Anyway, this is my interpretation. I read the statute as requiring display of a CPL any time it is demanded by a police officer, and since the law requires display there isn't any need for RAS. Adding the clause, "or any other person when and if required to do so by law" is a catch-all that covers any future changes to the law.
