Errors in testing

So a man who was arrested for possession of Methamphetamines, after two field test kits said that white flakes found on his floorboard were drugs, sues the city of Orlando after the state crime lab certifies that they were actually the frosting from a glazed donut and wins $37,500.

The problem here is that the cops use their own pocket knives to put the sample into the test kit. The knives are contaminated with drugs from previous tests. So the test turns out positive.

Cops should have to report when they screw up arrests like this, so a person arrested is able to bring up the cops error rate in court. Drug dogs, too. When the police department makes a mistake like this, at least part of the money should come from the cop's pocket.
