I pick up my loaner car and never look in the glovebox. I pull out of the dealership and drive down the road and make a right on red and get pulled over. Cop asks if I have any firearms in the car and I state no. He then asks for license and registration and I open the glovebox and there is a firearm. I just said one thing and it wasn't the truth. He then asks whose firearm it is and I say I don't know. I'd imagine he'd find that curious. He then takes possession of the it and runs the serial number and it was reported stolen or whatever. The stop rapidly escalates from a traffic stop into a firearm investigation, the gun gets seized, the driver is likely removed from the car and detained, and arrest becomes a real possibility even before anyone sorts out whether the driver truly knew the gun was there.In free states, and this happened with me, there is no "illegally owned" anything here. I am legally allowed to possess a gun.
The "was it used in a crime?" question is 100% irrelevant. Police can't LOOK at a weapon and determine this on the spot.
I just wanted to go to Costco in a loaner and now I'm dealing with this and that would make me unhappy. I don't live in Ohio and so what would happen to you there means nothing to me, just what would likely happen to me where I live. Is this every case? No, but it's perfectly plausible.
