I
almost had a big hassle about 5 years ago, when I drove down to the Port of Miami & Miami Florida then left my pistol case(which contained my loaded Ruger GPNY .38spl revolver) on the hood of my Chevy Cavalier.
An alert cab driver waved at me & pointed out my goof.
Mistakes can occur. Stress, fatigue, illness etc can cause mishaps but care should be taken with firearms/ammunition.
