14. Checking for Fingerprints
If the officer, while confronting the driver gets attacked or harmed in any way, or if the driver of the car manages to drive away, the police officer who tapped the taillight of that car will have left their fingerprint. If this is the case, when the driver who matches the profile of the criminal who drove off or attacked the officer is pulled over yet again, the next officer will just have to check for fingerprints in order to have the evidence needed to catch the driver. It’s tricky and slick, but it has actually helped protect the police.
