Bull sharks are the worst. Nasty, mean and blind. They bite anything they encounter, boats, motors, docks, kids playing in the surf. Plus, they do not mind fresh water. Pit bulls in the water.
Ya, I know. Been scuba diving up & down the Atlantic coast as well as the Caribbean (17 years). Never seen a GW. Ran into some Bull Sharks off Playa del Carman, Mex. Turbid water, poor viz, surf zone. In short, they had all the advantages.
Friends did see a no-sh-t GW off Morehead City, NC. Got some gread video of the beast ‘playing’ with the orange float on the end of the trail line. Last pair of divers to re-board had the fear of God put in them.
