Arrests are public record. They are on the county website and can be published elsewhere. You can google people and find their mugshots. On the internet forever. If not convicted perhaps it can be expunged from her criminal record but will remain on the internet. For example the shooter in Charleston is all over the papers but he has only been arrested, not convicted. And a breathalyzer/urine isn't covered under HIPPA. Her BAC was taken as part of a criminal investigation. Additionally, in many states a for the privilege of having the State issue you a driver's license that you agree to certain rules when it comes to suspected DUI.
