The most dangerous thing about diving in water where there are sharks, is driving to the beach. Or driving to the airport to fly to your dive destination. People are really bad at assessing risk. Big teeth are scary. Drivers in cars are far more dangerous. I get a thrill of fear when a shark comes close, but they don't like the taste of us any more than I like the taste of eggplant. Respect them and exercise caution, but don't let irrational fear rule your choices.
That said, I don't dive in murky water. What's the point? I dive to see the corals and the pretty fishes. Can't see them if the water's all muck.
