An Anaheim Hills high school teacher, in conjunction with a San Diego developer, has created an app that can be used to show the locations of sobriety checkpoints. Geno Rose, the teacher created the app after being stuck in a checkpoint with his wife and newborn son crying the backseat. It is a real time app that allows those who have the app to update info live for the other users. It can be viewed and purchased here : https://itunes.apple.com/us/app/dui-dodger/id429342604?mt=8
For those who criticize the app, the app serves the purpose of assisting sober drivers, just as well, as drunk drivers, and the evidence that a drunk driver is going to use such an app is entirely speculative. Sobriety checkpoints are illegal in 10 states, per that states Constitution. Those states are: Idaho, Iowa, Michigan, Minnesota, Oregon, Rhode Island, Texas, Washington, Wisconsin, and Wyoming. The United States Supreme Court decided in the case of Michigan Dept. of State Police v. Sitz that sobriety checkpoints, properly conducted, did not violate the United States Constitution. The decision was 6-3.
Justice Stevens dissent in this case was a powerful argument against such checkpoints: “This is a case that is driven by nothing more than symbolic state action — an insufficient justification for an otherwise unreasonable program of random seizures. Unfortunately, the Court is transfixed by the wrong symbol — the illusory prospect of punishing countless intoxicated motorists — when it should keep its eyes on the road plainly marked by the Constitution.”
