I started to write a reply to your comment expressing my confusion, when I realized I had wrongly assumed you were in the car and the police officer on foot. Once I realized the situation was reversed, I immediately agreed. Which makes me think there are two kinds of crimes. Crimes which are bad for their effects, and preventive measures. Of course there are grey areas, but driving and drinking is very close to doing actual damage, while walking and drinking is pretty much harmless. I think it's a shame no law system makes any difference between the two. It would also put a lot of the drug legislation in a different light.
