"Police said when arrived they let the driver go, but Reynolds was questioned and turned over to federal authorities.
Police turned over their investigation to the Department of Homeland Security.
So far, Reynolds hasn't been arrested or charged with any crimes, police said."

He probably has a concealed carry permit as well - not that that justifies his actions. If he in fact is an FFDO, he's violated just about every off-duty SOP I can think of. It behooves the local PD to sit down with DHS (and the airline) and figure out just what to do before they start "writing things down".

Now if I were the guy who got pulled over, I'd certainly have an attorney "discovering" just what the pilot's net worth is. Unfortunately, it probably ain't much.
