The question asked 6 years ago by the member who started this thread was are LEO informed that you have a concealed pistol license (CPL, Washington's name for it) when they check your drivers license, or in his words, are they linked. In Washington not only does your CPL come up but, whether or not you have a CPL, at the department's discretion, a list of the guns that you've received through FFLs also comes up.

That is to inform LEO en-route to a situation like a domestic dispute that there likely is a gun in the house.
