Keep Drunks off the road! They needed those check points set up, near where a density of Bars are located, in order to teach people a different behavior. That whould target the many DUI weekender's with addictive behavior. Privacy should only be an issue, if the searches are executed while you in your car, and on private property. Those driver's that are stopped on a public road, should be subject to a DUI check, in order to insure public safety. Allowing drunk driver behind the wheel, is like allowing a sh!t head to set up a firing range on our freeways and road,... only, the bullets used by these drunks, are 2 ton automobiles. Just hope that I am never in the cross hairs.
