Southeast Texas police didn't need a blood alcohol test to prove 25 year old Calli Dretke was driving drunk. She slammed into a police van, as officers were dealing with another drunk driver.Dretke tried to continue driving and slammed into two other police cars. One officer suffered a broken leg in the madness, meanwhile Dretke was arrested and charged with felony intoxication assault. She certainly wouldn't be considered a subtle drunk.
