At the start of the film, two Jerkass cadets are commenting about how many black people there are. Cue a reproachful look from Hightower (play by football star Bubba Smith), which makes them change their tune.
Then midway through the film, Hooks runs over the foot of one of the Jerkass cadets, who abuses her with racist comments. Even Harris knows that this is a bad idea, as Hightower calmly walks over to the cadet, who had by now locked himself in the squad car, and tipped it over for his remarks.
Cadet Leslie Barbara gets to be badass twice in the first film. The first time had him stand up for Mahoney after Mahoney had just saved him from the two cadets who had been bulling him all year. The second time has him beat the shit out of the gang that bullied him at the start of the film ( though it turned out they weren't stealing anything, they're moving out due to the city-wide riot, oops.)
Lassard taking out the diamond thief in Assignment Miami Beach, after being informed that its not a training scenario being acted out, but an actual hostage situation. There's a reason Cloud Cuckoo Lander Lassard rose to his high position in the first place.
Tackleberry showing up a mook with his marksmanship skill. The mook uses his submachine gun to create a Smiley face on a wall; Tackleberry uses his own to spell out "HAVE A NICE DAY" underneath it.
