A Florida sheriff's deputy is looking more like a cartoonish cop from "Reno 911!" on body cam footage of him mistaking an acorn hitting his patrol car for bullets ... prompting him to open fire on the vehicle.
The video, which was just released, shows Okaloosa County deputy Jesse Hernandez on the job, detaining a guy back in November for allegedly sending threatening texts. Hernandez and his partner cuffed the man and put him in the back of their patrol car.
All seemed to be going well, until Hernandez appeared to hear what he perceived as a shot being fired -- which catapulted him into a frantic drop and roll as he drew his weapon and started firing multiple shots at his car.
Hernandez seems to unload his entire clip ... and, remember, 22-year-old Marquis Jackson was helplessly sitting inside the patrol car, unarmed and completely restrained -- yet, Hernandez clearly thought Jackson had shot at him from inside the car.
