I remember posting about this back when it happened, but refresher story LEO's here in GA were using roadside instant drug tests with a high false positive rate. In Macon, the sheriff's dept pulled a lady over who had a bag of blue cotton candy in her car. Officers Billy Bob and Barney Fife desolved the blue cotton candy in the kit and it turned blue(shocker right) meaning it tested "positive" for meth. They proceeded to throw her in jail and set bail so high she couldn't afford to get out. She stayed in jail for 3 months and her life was basically destroyed before the case was tossed. She just had her lawsuit dismissed because the county apparently isn't responsible for their actions.

More than three years after a Macon woman spent months in jail when her cotton candy was mistakenly tested as methamphetamine, her lawsuit against the county authorities who locked her up was dismissed.
