I always assume every car I pass has at least one functioning, loaded gun in it.
I was looking at the numbers recently, and we are approaching 1 in 20 citizens with a ccw both here in Ga and in Fl. I have to think AL would be similar. And in ga you don’t have to have a ccw to carry in your car, it is considered an extension of your domicile.
So yes, a reasonable assumption.
