What's the Difference Between a Sheriff's Department and a Police Department, Anyway?

Someone from the Sheriff's Department in Austin, MN, called today and left a message. I was kinda confused about why they would be calling me.

I called back, but he was on a medical call somewhere.

Then he called me back again a bit later.

It was a short conversation, once we finally spoke. I guess there was some deal with a car being noted somewhere under suspicious circumstances, and the license plate the deputy took down was the MN license for my Taurus.

But...the Taurus has been here in Seattle for years, and it's not even registered in MN any more, it's registered in WA.

So, maybe someone got ahold of the old plates. Or the deputy took down the plate number incorrectly. Who knows.

What a strange mid-day diversion.
