Here's an LEO in Iowa Story:
An Iowa Friend/Training Associate/Permit-to-Carry-Weapons Holder was stopped by an Iowa State Trooper on I-29.
Friend ID'ed himself as a Packer; showed PCW credentials. [No Card; No Photo. Just a Little Green Piece of Paper in Iowa]
Trooper took possession of the handgun, placed it in cruiser. Then wrote a ticket.
Afterwards, Trooper returned the handgun to my friend and then sped off.
The handgun was in a plastic bag, field stripped. [All parts were there.]
The magazine had been emptied. [All rounds were in the plastic bag.]
I offer no further observations nor conclusions about this event. It simply happened that way.
