According to WBRZ.com, the man asking for help in the video is a local shrimp salesman who jumped onto the hood of a moving truck in Baton Rouge after the driver of the truck stole his business sign. The man in the truck drove off, toward a local police station, with the local shrimp salesman still on the hood of the vehicle.
No charges were pressed, but a comment on the local news story that goes along with the video sheds some light on why a man would jump onto another man's car because of a sign:
It's about time someone did SOMETHING. This is the gentleman that myself and the rest of the real estate world refer to as "the sign man." He's been stealing signs for years and years. Police won't do anything because technically, if a sign is on a public servitude, it is considered "litter" after a certain amount of time. The only problem is that he takes them no matter how long they have been there. Hundreds of real estate agents have reported him taking their signs during open houses, when city ordinances have clearly stated they can remain there during certain hours as long as they are picked up. This man's backyard, according to several eyewitnesses, has hundreds, perhaps THOUSANDS of signs. It's his hobby. He's been doing it for years. In some cases, it's a public service, but for those of us obeying the law, and the ordinances set up for legitimate business purposes, it's theft. He should be arrested.
