I believe Tom Arnold's character was telling Schwarzenegger from the beginning that he shouldn't be using government resources to investigate his wife's affair, but Schwarzenegger had dirt on his partner so he just went along with it.

I don't know if you remember the 90's very well cause a lot of action comedies were like this. It's goofy & it's supposed to be goofy. Also, there weren't a lot of females in Hollywood that had power, so obviously the female part wasn't written well majority of the time. The entire reason we have this feminist Renaissance in filmmaking now.
