Quite possibly not the sort of thing they're talking about, but there's a slightly notorious scene that was presumably intended to portray the police as racist and stupid, which in theory is probably a much more acceptable message now than then. Except it depicts the cop coming out with a stream of very OTT racial insults, played for laughs, and doesn't fit the current zeitgeist at all.
