The term "Ask a P'liceman" does not appear to be a recognized concept, organization, publication, or widely documented phrase in reliable encyclopedic sources. Accurate information regarding its definition, origin, or usage is not confirmed.
It may be a colloquial or slang expression, potentially derived from Cockney rhyming slang, where "P'liceman" is a phonetic shortening of "policeman." In that context, "Ask a P'liceman" could informally suggest seeking advice or assistance from a police officer. Alternatively, it might reference a historical phrase, a title of obscure literary or theatrical work, or a localized idiom, but no verifiable references support such uses.
Due to the lack of authoritative documentation, the term remains unverified and is not recognized in standard reference materials.
