That's one of the flimsiest excuses I've ever seen in a long time.
To ensure the person's identity because of identity theft?
Hello, doesn't the license, and insurance kind of rule out that possibility?
Then too, what about traffic court, does the cop not show up for traffic court?
Do they not have a photo on the driver's license? Or are they saying that people can steal both your identity AND your vehicle, without it being reported somewhere along the timeline?
Or is that they're afraid that in order to get out of a $20 ticket, people will en masse start reporting their vehicles and their id stolen the day after they've been pulled over in a traffic stop? What is the rationale here?
