Drunk driving checkpoints can be a bit controversial. While the police maintain that they're simply trying to keep people safe, the issue is that most OVI stops have to start with reasonable suspicion that the driver may be intoxicated. Police must have a reason to stop the car. Even if they don't think the driver is drunk right away, they need another reason, such as speeding, a seat belt infraction or a broken headlight.
A man who was once referred to as the "Top OVI Cop" in Cuyahoga County, Ohio, is now in legal trouble after he was indicted for allegedly lying on the witness stand and on his police report after arresting a drunk driver. That's perjury, and he's now facing serious charges after the grand jury's ruling, which means there is cause for a trial.
