If there is a violation, impound the vehicle.

From the PPA

>Impounded vehicles are not released until the driver presents certification of proper registration, insurance, and driver’s license. You must also pay the total amount due, including all outstanding tickets, fees, fines, and penalties before you can take possession of your vehicle.

Aaand its done! People did their job. The owner received their vehicle or maybe even located a stolen one. All without civil forfeiture which steals the property of legal owners with no cause and then sells it to profit the PPD.
