Factual error: There is absolutely no way that Internal Affairs would have any authority or power to shut down an entire police force because of stolen drugs. As in the plot of the film, that type of decision would be decided by the city council on a vote and approved by the mayor. In any case, an extensive investigation would take place and the culprits would be arrested and prosecuted. No police force would be disbanded because of this absolutely fictional scenario.

Continuity mistake: When the two female characters enter the fancy hotel room, they make a point to say they will only be there for a couple of minutes. It is daylight when they go in. The visit is cut short (the one that's supposed to be a few minutes long) because of a gun battle in which one of the women dies and the other escapes. The escaped one gets out through the roof into an evening's sky. There's still light visible, but for a visit that lasts all of 4 minutes, it's far too quick a change. (00:23:00)
Mike Lowrey: You know you drive almost slow enough to drive Miss Daisy.
Trivia: Pretty much all of the dialog between Martin Lawrence and Will Smith was ad-libbed. The original script can be found here: http://www.imsdb.com/scripts/Bad-Boys.html, as Don Simpson and Jerry Buckheimer thought it would be better and more funny.
