According to a new report, Riggs-Hopkins was reprimanded after an investigation showed she acted in good faith, but improperly conducted parts of the drug test.
Police said two of the three tests were positive. But in the end, the crime lab found no drugs.
Law enforcement consultant Chuck Drago said that a field test can be wrong, which is why officers should look for additional evidence to justify an arrest.
“Something that would give some indication that this might be a drug,” he said.
Drago also said a supervisor should have questioned the arrest report.
Riggs-Hopkins later received training on how to conduct the drug tests.
In the wake of this case, Orlando police ordered that every officer in the department take a review course on the field drug tests and pass a follow-up exam.
