When I lived in the DC area some officials in Maryland announced that there had been entirely too many fatal crashes caused by drunk driving. They also asserted that the main cause was that people would buy a bottle of hard liquor and then stop into a 7/11, buy a cup of ice, pour the liquor over the ice and go on down the road, sipping away and getting drunker and drunker.
Obviously, the answer would be to increase enforcement, increase penalties, and maybe even put up sobriety checkpoints. But I strongly suspect that such actions would be found to be unacceptable when it was discovered that too many of the "wrong people" were being arrested.
So they came up with an alternative approach and put a motion on the ballot to:
OUTLAW THE SALE OF CUPS OF ICE!
It did not pass.
