Why not get your two ticketless friends, drive to the PD with them and have them ask the cops for their tickets? I mean this all about fairness right? You want to make usre they get tickets to. Your blaming the cop and worried about fainress (which I am sure you have not voiced to yoru friends). If you take your friends in and demand their tickets, you can get what you want.
Seriously, that is your concern right now? You might want focus on more important things. Like you ability to make multiple poor decisions in one night, such as you went to a party, drank, didn't plan a sober ride home, knew a minor was drinking, and then got in a car and gave somebody else they keys who was under influence, leaving the only sober person a victim in a back seat. Bunch of great decisions that night. And now you are worried about making sure your two friends get tickets? They aware of your concern?
-In God we trust. All others, put your hands on the car and don't move.
