During the expose segments, the ones with profanity are always edited out. Also (part of the regular news), Russ had an famous interview with Mike Tyson, but it was edited out too.
For some the segments of Matthew Schwartz, they're a bit more for leisure, so theoretical Cinemax content advisories for a best of segment of his exposes, which feel like "Richard Bey" episodes: rated TV-14 for violence (V), adult language (AL), and adult content (AC).
However, as UPN's first incarnation got closer to its end in 2006, the UPN 9 WWOR news stories got more profane as the news reports got sensational. So it depends on the era of UPN 9 news.
