And in my first point I'm saying maybe that person was never going to get behind the wheel in the first place. So now you've got a cop who is hassling someone who hasn't done anything wrong yet, which is certainly bad for community relations and possibly not even legal, depending on the circumstances. (And let's face it, drunk people aren't generally the most reasonable and level-headed when confronted, so it'll probably escalate and they'll end up arrested anyway.) Plus it pulls his attention away from the 6 other drunk guys who walked out right after and got into their cars. And if we're delegating personal responsibility, where's the bartender's obligation to prevent it in all this? Or the wingman? Or [insert everyone else but the drunk person here]?

Look, in general terms, I'm with you. But in this scenario, as I've said, I've got zero issue with the approach this cop took. His obligation is to protect the innocents (aka everyone else on the road), not the guy who cares so little about whether he kills someone that he can't be bothered to text a friend instead of getting behind the wheel.
