As they race down a back road, the guys are pulled over by a local sheriff.

What they did not count on, was the local sheriff.

They turn the stamps in to the local sheriff's office the next morning.

"The local sheriff is looking into all of that, naturally."

My advice is turn over everything you've found out to the local sheriff and let him handle it.
