You can spin it however you want, and you can point out all the little insignificant potential side-issues and distractions you want, but the fact remains that actual guilt is unimportant to you. You are willing... I would almost say eager... to randomly assign guilt to people who aren't even doing anything wrong. Shoot, on so many issues you prattle on about personal responsibility, but on other issues like this you're willing to toss aside personal responsibility in the name of expediency. Expediency is not justice. Citing Joe for the actions of Frank doesn't teach Frank squat.
If the owner of the vehicle is in the passenger seat and the driver gets a speeding ticket, do we cite the owner? No, we don't. Why? Because it's not right or fair. The owner was not the one who was committing the offense, and we know and recognize that. If the owner of the vehicle loans their vehicle to a friend, and the friend gets a speeding ticket from a flesh-and-blood police officer, do we cite the owner? No, we do not. Why? Because it's not right or fair. The owner was not the committing the offense, and we know and recognize that. Do you believe that the vehicle owner should be cited in these situations as well? You do if you're consistent. If not, why not? What's the difference?
It's not a hard concept to grasp: loaning a vehicle to an otherwise currently legally licensed driver is not a crime.
