I can't speak for the entire state, but around "my part" (west central AL...Tuscaloosa, Fayette, Lamar, Pickens, Green, Hale counties etc.) of the state, YOU WILL GO TO JAIL if you OC.
"let you slid" if you're hunting, fishing etc. but even then, you will likely be asked for your permit.
I know that "technicaly", AL is an open carry state but, LE doesn't seem to understand (or maybe don't care) what the laws/courts say.....I've had a CC permit for 30 years and the attitude has always been this way.
Before the flames start, please understand, as much as I'd like to see things changed, I don't have the financial resources to "make a stand".
