Leon Rippy's henchman character wears a shirt on which is his own mugshot from a previous arrest. Kuffs is nothing if not self-aware. Had I been 16 instead of eight when this came out, it might be in my favorites.
Completely a movie of it's time, for better and worse. The whole notion of private police being a good thing, yeahhh, not sure how that holds up in 2019. The other "problematic" issues are whatever, mostly glossed, meaning they're not mean-spirited enough to matter. Kuffs never takes itself seriously enough for them to. That's a good thing. It is genuinely funny in several parts, overshadowing any and all the nonsense.
FYI: The scene with Slater and Goldwyn in the car exchanging f-bombs that are blotted out by car noises is hilarious, capped with a sublimely great punchline.
