I don't see how checkpoints on nights when more accidents happen because of drunk driving, such as holidays and such, is such a HUGE ordeal in our society. By that thinking, you should be against what we have to go through at the airports these days, are you?
Hildy,
Checkpoints catch something like 1/4th as many drunks as roving patrols and don't violate anyone's rights.
If you are interested in getting drunks off the road, you should be against checkpoints.
BTW, I have flown only once since 9/11. I do find those checks to be intrusive as well as discriminatory towards those least likely to cause a problem. Checkpoints are exercises in obedience training and I choose not to participate. If I can't drive in a reasonable time, I don't go.
