In People v. Snead, 160 Misc. 2d 466 (Dist. Ct. Nassau County 1994) every car was stopped at the checkpoint, thus tending to point to its nondiscriminatory and nonarbitrary manner. (Id. at 468.) In that case no guidelines existed to ensure that the sobriety checkpoint in that case was conducted in a uniform and nondiscriminatory manner. (Id. at 469.) The court sustained the checkpoint based on the officer's prior DWI [driving while intoxicated] detection training and its belief that the state trooper "exercised no more or less discretion than he would have had he stopped defendant as a result of a traffic infraction." (Id. at 468-469.)
