Oh no, that kid told you to shut up! You should probably lose your cool, beat the fuck out of him with a billy club under the cover of being a police officer (whose primary function, last time I checked, was to keep the peace) and then justify it as necessary b/c the kid talked out of line.
Makes sense. Let's keep beating people.
Don't follow protocol and ask the kid to step out of the car, tell him he's being arrested for "reason A", cuff him, give him Miranda, and then put him in the back of the squad car. That'd be too easy.
