To me it sounds like they were all riding around high late at night, probably saw a car with some college guys in it and thought it would be funny to mess with them a little bit as somewhat of a joke. Stupid decision. This could be an entirely different situation if the victoms were people the three of them knew from school and were just playing a joke on. I really doubt this was premeditated and that they were in it to get their hands on a bunch of cash. I mean the victims were in a '98 Honda for god sake.
It just all adds up to being a prank that got blown out of proportion because somebody from a distance saw what looked like your typical armed robbery, called the police, and thats probably why Jackson said "we gotta go" realizing it was about to turn serious. It all points to that. The cheesburger joke, the girl in her car laughing, the guys not wanting to press charges, them smiling about it. It was still a dumb move though even if it was intended as a joke no doubt....especially that late at night, and with pot in the car.
