Unidentified series "cop" — S1E4

An episode of an American television series that this collection files only under an abbreviated code. The season and episode numbering is unambiguous and is recorded here; the series itself is NOT identified, because the abbreviation alone is not evidence and this one's episodes-per-season pattern does not single out a series. Several codes in the collection run twelve or thirteen episodes a season, which matches a great many cable series and distinguishes none of them. Code "cop", season 1, episode 4.
