Where can you not carry a concealed pistol, even with a CPL in Washington State?

Carrying a concealed pistol is prohibited in areas designated as federal facilities or properties in accordance with federal law. These areas include buildings or properties owned or leased by the federal government, such as federal courthouses and post offices. A CPL (concealed pistol license) in Washington State does not grant the holder the right to carry a concealed pistol in these designated areas. Options A and B may also restrict concealed carry, but these restrictions may vary by state. Option D is incorrect because option C specifies federal facilities, which may not align with state-specific restrictions.
