I didn't intend to be discussing the issue of "operated" one way or the other when quoting the AG opinion. I was just pointing out that we do have at least some definition of "intent to go armed", which Falcon1 brought up. So, I think we would probably not be at great risk for the felony charge simply by having a handgun stored in a vehicle.

My questions were asked with the thought that if an unloaded, inaccessible handgun doesn't meet the legal definition of "weapon" or "firearm", then the part about "operated by the adult" is immaterial.
